Grid electrical-energy quality control and direct-current bus voltage pulsation suppression, based on a small-capacitance active power decoupling circuit, of the driving system are decoupled from each other, such that the complexity of a system controller is effectively reduced, and a harmonic standard related to grid electrical-energy quality is met while implementing the high-performance operation of a motor.
