Abstract
- This paper introduces a direct PWM split-phase boost ac-ac converter with a high voltage gain, natural output voltage balancing, no duty-ratio limitation, and no commutation problem. Although under unbalanced load conditions, the two output voltages still are equal without auxiliary circuits and/or any dedicated controller. Moreover, the input current ripple is significantly decreased due to the interleaving effect. With a proper asymmetrical PWM scheme, the converter can work in the entire range of the duty cycle. In addition, the commutation (dead-time) problem is eliminated. The operation of the proposed structure is validated with a 500 W prototype converter. Experiment results obtained under various load conditions such as inductive, nonlinear, extreme load, and load scenarios are also provided. [ABSTRACT FROM AUTHOR]
