This document compares PSpice and LTspice simulations of BJT circuits. It examines the hFE characteristic of a BJT by varying the input current from 10mA to 10A and measuring the ratio of output to input current. It also examines the output characteristic of a BJT by varying the input voltage from 0V to 5V and measuring the output collector current, which increases linearly from 0A to 2.4mA over that range. The document provides circuit schematics and output graphs to demonstrate the simulations in PSpice and LTspice.
HEV-Inverter Ni-MH and Lead-Acid Battery Using PSpiceTsuyoshi Horigome
?
The document describes PSpice simulations of an HEV inverter circuit with both Ni-MH and lead-acid batteries. For the Ni-MH battery simulation, the circuit includes two 50F Ni-MH batteries at 100% state of charge, supplying a 100A load. A 315uF capacitor is added to reduce noise. The lead-acid battery simulation uses a similar circuit, but with 50F lead-acid batteries and a 345uF capacitor. The results shown are speed, state of charge, battery voltage and inverter output voltage.
How to Design of Power Management of Hybrid Circuit(Battery and Capacitor) us...Tsuyoshi Horigome
?
This document discusses power management of hybrid circuits using batteries and capacitors in PSpice. It presents four methods: 1) circuit method, 2) battery-only system, 3) battery and capacitor system, and 4) conclusions. The battery-only system shows the battery voltage and state of charge over time handling varying current loads. The hybrid system uses a capacitor to handle peak loads over 4A while the battery manages lower loads, improving the battery state of charge. The hybrid circuit better handles quickly varying high current loads.
