l design must be verified by using Multisim at the component level, that is, with transistors, diodes, resistors, inductors, capacitors, digital gating signals, etc., instead of block diagrams. You may want to use the IRF510 MOSFET transistors for the H-bridge, IRF840 MOSFET transistor, and the MBR10100 for the buck converter, and the 1BH62 diodes for the rectifier. Note that proper filters are required
