Single Phase Step-UP AC Voltage Regulators with High Frequency Link

In this paper a step-up ac voltage regulators with high-frequency link are proposed. It consists of input LC filter, energy-storage inductor, input cycloconverter, high-frequency transformer, output cycloconverter and output filtering capacitor. In the proposed topology the regulators can convert an unstable sinusoidal voltage with high with high to a stable sinusoidal voltage with the same frequency and low distortion. The results of proposed regulators have advantages of high-frequency galvanic isolation, bidirectional power flow, high efficiency, and high reliability.
