The article makes a comparison among different types of bus, bus transmission signal and several familiar topologies of front-end converters and load-end converters. Finally, the half bridge converter with full-wave rectifier based on the high-frequency parallel-type AC bus bar is chosen as circuit structure and optimized. The working mode under different condition of the circuit is analyzed and a mathematical model is set up under continuous current mode. Simulation result is used as comparison.
