It contains the fundamental wave proportional to the amplitude and amplitude of the sinusoidal modulation wave, and the higher harmonics of the carrier frequency, but does not contain the lower harmonics. Due to the action of the input inductor L s on the AC side, the current ripple caused by the higher harmonics is filtered out, and the frequency of the sinusoidal modulation wave is controlled to be the same frequency as the Power Source, then the input current is
At the same time, two boost chopper circuits are composed of VT 2 , VD 4 , VD 1 , Ls and VT 3 , VD 1 , VD 4 , and Ls , respectively. Taking a circuit composed of VT 2 , VD 4 , VD 1 , and Ls as an example, when VT 2 is turned on,
Above
When the VT 1 , VD 3 , VD 2 , Ls and VT 4 , VD 2 , VD 3 , Ls respectively form two step-up chopper circuits, the working principle and
