The single-phase full-bridge inverter shown below is operated in the quasi-square-wave (QSW) mode (phase displacement control) at the frequency f= 50 Hz, with phase shift between half-bridge output voltages Vao and Vbo. The load is an R-L load with R = 5 2 and L= 10 mH. (a) For B= n/2 sketch v, and find its rms value. (b) For B= 2/3 find the rms values of load current harmonic components with orders n = 1, 3, 5, 7. (i.e. find Ion,rms, n=1,3,5,7) (c) Find approximately the total harmonic distortion (THD) of i, using the results in part (b). + V= 200 V KH + Va0 KH Vo load Vbo KH The single-phase full-bridge inverter shown below is operated in the quasi-square-wave (QSW) mode (phase displacement control) at the frequency f= 50 Hz, with phase shift between half-bridge output voltages Vao and Vbo.
