Cost Effective Design of Power Converter for Three Phase Motor Driver

The project is to make a design that uses inexpensive parts that are ready available/in-stock for a power converter/controller to drive three phase motor on 48 VDC. The controller will have a microcontroller to implement the control algorithm, and a power converter to perform fast switching three phases (upon switching signals) handling about 1 kW total. The switching scheme will follow classic asynchronous switching with three states: positive, zero and negative.
