摘要：

This presents an LLC resonant DC-DC converter for high output voltage applications. The proposed converter consists of four main parts which are a full bridge (FB) inverter, a resonant tank (LLC), a high voltage transformer (HVT) and a HV bridge rectifier. The proposed converter can regulate the output voltage by narrowly varying the switching frequency. The LLC resonant circuit is utilized to retrieve the energy trapped in the leakage inductance of the transformer and to achieve the zero voltage switching (ZVS) feature. The resonant circuit also increases the conversion efficiency. A low power prototype of proposed converter is implemented to verify its benefits. The experimental results from the laboratory prototype are given to validate the operation of converter.
