19. Power Electronics and Drives (PED) Analysis and design of 50W SMPS for AM radio (PED 9+10) The SMPS should be able of operating at an input voltage of 276-375[VDC], and at a switching frequency above 1.5[MHz] using a PCB transformer. The use of PCB transformers in both the gate drive circuit and the converter were a success The parasitic capacitances of the transformers caused the transformer voltages to contain considerable resonance, which will need extra attention. The SMPSoperates at 300[VDC] and at 1.75[MHz], with an overall efficiency of 70%. Industry: B&O

20. Power Electronics and Drives (PED) Design of a Low Cost, Modular Frequency Converter for Three Motors (PED 9+10) The project deals with a cost effective design of a modular frequency converter. The purpose is to control up to three independent motors, sharing a common DC-link and one micro-controller. The design is constructed and verified with subsystem models of the whole system built in Matlab/Simulink. A prototype of the modular frequency converter is also built and the design verified in the laboratory. Industry: Marel
