Background: Insulated Core Transformer (ICT) used in irradiation industry has many disadvantages on account of its low operating frequency

Planar Insulated Core Transformer (PICT) is developed for high-frequency high voltage direct current (H-V DC) generator. Purpose: This study aims to develop a novel PICT-based H-V DC for power supply less than 1 MeV

and investigate its output characteristics for the design and optimization of PICT. Methods: Preliminary test on self-designed PICT apparatus is carried out and the output characteristics under different loads are measured. Both theoretically and by Multisim PICT’s equivalent circuit and parametric model are built and the reason giving rise to voltage drop is analyzed. Emphatically

the influence of stray parameters to the output characteristics is discussed and experimental verification is also presented. Results & Conclusion: Leakage flux causes voltage drop when the load current is heavy. To eliminate the leakage flux

power coefficient must be rectified by compensation capacitor

and the relevant experimental verification shows satisfactory results. And Multisim simulation is considered to be practicable in physical design of PICT in view of good consistency with experimental result. Abstract
