A Review on VHF Power Electronics Converter and Design Issues

By N. Z. Yahaya, K. M. Begam and M. Awan


Abstract—A high output power density VHF converter has become important in recent years. This output power density of the converter is experiencing an adverse effect resulted from the applied switching frequency. In addition, the frequency which is higher than 20 MHz will no longer be applicable on the discreet SMT technology hence lowers the output power density. Thus, further improvement on circuit analysis and PCB layout design could help in the improvement of higher operating frequency. Even though it is suggested that power density and efficiency do not necessarily require a high switching frequency to achieve, the resonant network topology still has to be considered. In spite of issues resulted from the VHF converter design, power device selection and PCB layout circuit design are among the critical factors to consider, to maximize the capability of frequency-output power product in the VHF converter applications
