PWM Current Source Converters

The operation and performance of current source inverters and rectifier modulated by SHE.

When input current from DC power supply or DC capacitor is maintained constant regardless of the voltage and current requirements at the load, the converter is called Current Source Inverter (CSI). When input current from AC power source is kept constant regardless of the changes in the out load, the converter is called Current Source Rectifier (CSR).
We are investigating the operation and performance of current source inverters and current source rectifier, both modulated by selective harmonic elimination (SHE) schemes.
Inverter with Selective Harmonics Elimination (SHE) modulating scheme is used. SHE pattern to selectively eliminate 5th, 7th and 11th harmonics with no bypass pulses.
Rectifier with SHE modulating scheme using the given angle values from the table in the textbook is used for eliminating 11th and 13th harmonics.
