Abstract
The triangle carrier based pulse width modulation (TCB-PWM) can be functionally equivalent to space vector base PWM (SVB-PWM). For multi-level inverter, it is very difficult to realize the SVB-PWM because its vector space is very complex. In this paper, a unified TCB-PWM strategy for three-phase N-level diode clamped inverter, including continuous PWM (CPWM) and discontinuous PWM (DPWM), is proposed. With the proposed strategy, the final modulation signals can be easily obtained by twice common mode voltage (CMV) injections. The PWM driver signals are generated by comparing the final modulation signals and phase deposition triangle carriers. Especially, the procedures to realize different types of PWM method are demonstrated in this paper. The proposed method can be directly implemented in digital processers.
