Abstract :
A new interleaved three-level inverter with reduced ripple current of filter inductor is proposed. This inverter consists of six power switches, including two interleaved power switches at the top location and the bottom location separately, and two double frequency power switches at the middle locations. The inverter theory and PWM method are explained. The ripple current expression equations of the proposed inverter and other two half-bridge inverter are derived and compared. A two-loop control strategy with disturbance forward suppression loop is proposed and adopted. A prototype verified the proposed inverter.
