Abstract
This paper describes the PWM cycloconverter which can provide step-up ac-ac direct conversion in a wide output frequency range. With input reactor and output capacitor. the input and output ports are exchanged. And sine PWM scheme is applied to the converter. To analyze the converter operation the state equations are derived using dq transformation. Simulated results show that both the output voltage and frequency can be controlled by adjusting the modulating functions.
