Question

Draw the circuit for a three-phase full-bridge non-isolated inverter. Describe how the converter works using switching waveforms. Include a description of two different control strategies using PWM and square-wave phase difference methods. Clearly define the amplitude and frequency modulation indexes in the PWM method. Discuss and calculate the rms phase and line voltages when the DC input voltage is 400V.

Answer #1

A single-phase full-bridge inverter supplies a load of 10 W in
series with an inductance of 31.8 mH. The inverter is supplied by a
380 VDC source.
(a) Sketch the inverter circuit as described above.
(b) Calculate the rms value of the fundamental (n = 1) of the
inverter output voltage assuming it is a square-wave.
(c) Assuming a quasi square-wave output voltage waveform with a
delay angle of 45°, calculate the rms value of the fundamental and
the two...
