Introduction:
This is an example for a single phase Voltage Source Inverter circuit. This design shows the usage of IGBT as the switching element and generation of the PWM signals to drive the IGBT circuit. Varying frequency modulation ratio (mf) and/or amplitude modulation ratio (ma) controls the PWM signal and hence the load voltage.
mf = frequency modulation ratio (= carrier frequency/modulation frequency)
ma = amplitude modulation ratio (= vcntl/vtri)
