摘要：
A novel high-frequency and high power density planar insulated core transformer (PICT) applied to high voltage DC generator is introduced. PICT's operating principle and fundamental configuration are described, and preliminary experimental results in self-designed PICT apparatus are presented. Emphatically, magnetic leakage flux (MFL) giving rise to the output voltage drop is analyzed in detail both theoretically and by finite element method (FEM). Showing good consistency with experimental result, FEM simulation is considered to be practicable in physical design of PICT. To cancel out leakage inductance and improve the voltage uniformity, compensation capacitor is adopted and experimental verification is also presented. All shows satisfactory results.
