The algorithm yields low commonmodevoltage and current, acceptable PWM ripple at the input and output of the inverter, and has no overvoltage problems unlike AZSPWM1.
Used the switched capacitor CommonMode Feedback circuit(CMFB) in main amplifier to achieve a large outputvoltage swing and decrease the static power consumption at the same time.

The high precision and large current controller are used widely. But in the situation where there is high common-modevoltage, the detection circuit of the output current is very complex.
