The document discusses switch mode power supplies (SMPS) which are used in computers. An SMPS takes a single AC input and converts it to multiple DC outputs required by different computer components. It provides efficient power regulation by converting AC to DC and regulating voltages like 3.3V, 5V and 12V used by the microprocessor, chipset and disk drives respectively. The document also describes the different types of power supplies and connectors used in older and modern computers.Study of power supply used in computers

SMPS (switch mode power supply) converts AC voltage to DC voltage to power computer components. It uses a fan to dissipate heat. SMPS has input sockets for AC power and sometimes provides output AC power to monitors. It supplies DC power to devices through connectors on the motherboard and peripherals like ATX, peripheral, floppy drive, and Molex connectors. Splitters are sometimes used to provide additional power connections when there are not enough built-in connectors.Deep dive into_pc_power supplies_2019

The document provides information about PC power supplies:
- Power supplies are the most failure-prone and replaced component in PCs. A malfunctioning power supply can cause other components to malfunction or be damaged.
- Power supplies convert electrical power to energy for components using constant voltage switching regulation to output steady voltages regardless of input.
- Power supplies have independent voltage rails (+3.3V, +5V, +12V) to power different components, though cheaper models have less independent circuitry.
- Form factors like ATX, SFX, EPS define standard sizes for compatibility and replacement of power supplies. Larger power supplies use EPS formats.Power Supply

A power supply converts high voltage alternating current (AC) from a wall outlet to lower voltage direct current (DC) needed to power a computer. It regulates voltages like +3.3V, +5V and +12V and protects the system from overloads. Standards like ATX define form factors and connectors to ensure compatibility between power supplies and computer components. Power supplies are rated based on their ability to continuously supply power on the +12V rail, which powers today's processors and graphics cards.Power Supply

The document discusses power supplies and voltage regulation for embedded systems. It describes how AC voltage from wall outlets must be converted to lower DC voltage and how this can be done using AC adapters, plug packs or by incorporating a bridge rectifier. It also discusses using linear regulators and switching regulators to provide a constant voltage from a varying power source like a battery. Linear regulators are simple to use but less efficient while switching regulators require more components but are more versatile. Low dropout regulators consume less power and are well-suited for low power embedded applications.Unit 3- power supplies

The document discusses power supplies and the differences between IDE and SATA interfaces. It provides details on how power supplies work, converting alternating current to direct current and regulating voltage. While SATA allows higher bandwidths than IDE, a SATA hard drive is not necessarily faster as most drives cannot sustain speeds above IDE's maximum throughput. The key difference is that SATA uses fewer pins and a simpler serial interface compared to the older parallel IDE interface.

This presentation delves into the systemic blind spots within pharmaceutical science and regulatory systems, emphasizing the significance of "inactive ingredients" and their influence on therapeutic equivalence. These blind spots, indicative of normalized systemic failures, go beyond mere chance occurrences and are ingrained deeply enough to compromise decision-making processes and erode trust.
Historical instances like the 1938 FD&C Act and the Generic Drug Scandals underscore how crisis-triggered reforms often fail to address the fundamental issues, perpetuating inefficiencies and hazards.
The narrative advocates a shift from reactive crisis management to proactive, adaptable systems prioritizing continuous enhancement. Key hurdles involve challenging outdated assumptions regarding bioavailability, inadequately funded research ventures, and the impact of vague language in regulatory frameworks.
The rise of large language models (LLMs) presents promising solutions, albeit with accompanying risks necessitating thorough validation and seamless integration.
Tackling these blind spots demands a holistic approach, embracing adaptive learning and a steadfast commitment to self-improvement. By nurturing curiosity, refining regulatory terminology, and judiciously harnessing new technologies, the pharmaceutical sector can progress towards better public health service delivery and ensure the safety, efficacy, and real-world impact of drug products.Mate, a short story by Kate Grenvile.pptx

Session | Own Your Autonomy The Importance of Autonomy in Project Management
#OwnYourAutonomy is aiming to be a global APM initiative to position everyone to take a more conscious role in their decision making process leading to increased outcomes for everyone and contribute to a world in which all projects succeed.
We want everyone to join the journey.
#OwnYourAutonomy is the culmination of 3 years of collaborative exploration within the Leadership Focus Group which is part of the APM People Interest Network. The work has been pulled together using the 5 HPTM速 Systems and the BTFA neuroscience leadership programme.

15 SMPS.ppt simple mail protocol systeyk
- 1. SMPS SMPS is the Switched Mode Power Supply circuit which is designed for obtaining the regulated DC output voltage from an unregulated DC or AC voltage. Switch mode power supply is a linear power supply. There are four main types of SMPS such as. DC to DC Converter. AC to DC Converter Fly back Converter (The Fly back converter is used for Low power applications. ) Forward Converter
- 2. Block diagram of SMPS
- 3. 1.Input Rectifier stage: It is used to convert AC to DC.
- 4. SMPS
- 5. SMPS parts and Connectors Power-IN. The power-IN connector as shown in the figure is the input for MAINS supply. A power cable is inserted here, the other end of which is connected to mains supply. The input supply gets converted to DC supply. Power-OUT. The power-OUT connector is connected directly to the Power-IN connector from inside the supply unit. It supplies the same AC supply that is fed to power-IN socket. The power-OUT connector is used to give supply to monitors or any display unit. FAN. If you look at the back side of Computer-SMPS, you will find a FAN at the right side. The FAN as you can see, blows the air out and is only used to dissipate the internal heat from the SMPS since the switching is done at high frequencies which create a lot of heat inside.
- 6. ATX connector As you can see in the image, it is a 24-pin female connector which is used to supply DC supply to the motherboards. Various color-coded wires connect to this connector and each colored wire supplies distinct DC voltage which is explained in the chart below
- 7. . Wire Colour DC Voltage Red +5V Yellow +12V Black Ground Blue -12V Grey Power Good Green Power On Purple +5V Standby Orange +3.3V Brown/Orange White +3.3V Sense -5V(Optional)
- 8. ATX-12V connector. Latest SMPS power supplies are accompanied by an extra 4-pin connector which supplies 12 volts to energize the central processing unit and other components of the motherboard.
- 9. AT Connectors. Earlier motherboards used to support AT connectors( 6- pin each) also called P8 and P9 connectors to supply power to these motherboards(upto 486 boards)
- 10. . Wire Colour DC Voltage Red +5V White -5V Black Ground Blue -12V Yellow +12V Orange +5V(PG)
- 11. 4-PIN connectors. There are multiple 4-pin connectors that draw out from the SPMS unit. These connectors are used to supply DC power to various peripherals of computer like a floppy disk drive, hard disk drive or DVD- writers.
- 12. Connecting to Drives Pin Number Wire Color Signal 1 Yellow +12 V(Used in motor) 2 Black +12 V Ground 3 Black +5 V Ground 4 Red +5 V(Used in logic circuit)
- 13. SATA-output connector. To feed the power to latest SATA hard drives, these connectors are used.
- 14. How to test computer SMPS To check the supply, whether it is working properly or not, you can test it before fitting it in the cabinet. There is a simple way to test the SMPS, you just have to short the green wired connector to any black colored(ground) connector. If the SMPS is working perfectly, the fan of the supply will start working
