Abstract
A 2 kW single phase PFC active IPEM (integrated power electronic module), consisting of full bridge rectifier diodes, current sensing resistor and boost converter, has been developed employing CoolMOS and SiC diodes in this paper. The electromagnetic interference mechanism in the module is demonstrated. In order to reduce the voltage spike of power devices, three different design patterns are compared for reducing the parasitic self-inductance of critical loop. The approaches for reduction in inductive interference between power critical high di/dt loop and driver testing loop are investigated, including flux cancellation pattern for power high di/dt loop, reduction in electromagnetic interference source and inserting a copper shielding layer between them. Finally, the electrical design considerations are verified by the simulation and experimental results
