Design and Implementation of 4-Stroke Topology in Electric Drives

Retianza, Darian Verdy January 2018 (has links)
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. / 4-taktsomvandlarens topologi undersöks och implementeras i dennaavhandling som en metod för att dämpa oscillation när reverse recoverysker i slutstegets MOSFET. Syftet är att dämpa elektromagnetiskstörning från kraftomvandlaren. Designprocessen är att analyseralämplig induktans, göra en simulering i LTSPICE och designa ett högpresterande6-lager PCB för kraftiga strömmar. Slutligen testas prototypenmed olika kontrolltider, elektromagnetisk emission och elektromagnetiskkonduktion.
