Abstract

This paper investigates a modular high frequency high voltage (HV) power supply architecture with planar transformer to achieve compact size and high efficiency. The insulation stress and voltage distribution different architectures with planar transformer are analyzed in firstly. An optimized modular high frequency HV generator architecture with planar transformer is proposed with even voltage distribution, low high frequency AC stress, easy insulation design and good thermal performance. The HV insulation and electric design of the HV planar transformer are provided. A prototype with 300kHz 4kW 140kVDC HV power supply with modular HV generation architecture and planar transformer is built to validate the concept finally.
