Abstract
The paper explores the spontaneous coupled clamping-capacitor-current contr ol loops and the resultant self-balancing property of the clamping-capacito r-voltages in the multilevel capacitor-clamping-inverter. The case of the t hree-level capacitor-clamping-inverter under sub-harmonic PWM modulation is dealt with first. The case of the multilevel capacitor-clamping-inverter ( M > 3) under sub-harmonic PWM modulation is then analyzed. Test results on a half-bridge three-level capacitor-clamping-inverter prototype under sub-h armonic PWM modulation are demonstrated in the end.
