Medium-high frequency isolation converter power module

The invention provides a medium-high frequency isolation converter power module. On the condition of comprehensively considering wide-range input voltage and load change, isolation, high power density and limited space constraint, optimization design including a power assembly module, high-frequency resonance isolation rectification, a low-inductance power link, heat source device radiator layout, overall heat dissipation space, a low-resistance capacitor chain, comprehensive compact layout and the like is carried out. Resonance parameters of the power module of the medium-high frequency isolation converter can be modified by changing the number of capacitors connected in parallel, the laminated busbar adopts an L-shaped design structure, stray inductance is effectively reduced by means of the coupling principle, the structure is compact, parameters are adjustable, the switching frequency and power density of a system are effectively improved, and the reliability of the system is improved.
