DC Power Generation Systems with Permanent Magnet Synchronous Machines and Full-Bridge Rectifiers Using Resonant Circuits

Abstract

Series hybrid vehicles use power generation systems with engine-powered generators and rectifiers. Systems with permanent magnet synchronous machines and full-wave rectifiers are expected to be efficient and inexpensive. However, it is difficult to increase the output power density of the generator because the generated voltage cannot be increased beyond the induced voltage by permanent magnets. This paper describes the process of improving the power density of a system by adding capacitors to the system to form a resonant circuit.
