Abstract: The 4-Stroke inverter topology is investigated and implemented in thisthesis as a method to damp the oscillation at the MOSFET drain-sourcevoltage when reverse recovery occurs. The aim is lower ElectromagneticInterference source level from the power inverter. The designprocess is coming from analyzing the appropriate inductor, making asimulation in LTSPICE and making a high-performance six-layer PCBfor the high current application. Finally, the prototype is tested in differentcontrol timing, radiated emission test and conducted emissiontest.
