Abstract

The hybrid IPEMs (integrated power electronic modules) for front-end converter in distributed power system are described in this paper. Three individual modules, including PFC module, DC/DC module and DSP control board module, were developed to constitute the IPEMs. The conventional wirebond, and spring stress contact technology for control and sensing signals, are employed in module fabrication process. And the structure of the IPEMs is demonstrated. The 1 kW PFC and DC/DC converter modules where CoolMOS and SiC diode are employed, are prototyped, And the digital control based on DSP chip is implemented. The thermal performance of the module is simulated with ANSYS. The electrical and thermal performance of the module has been also validated theoretically
