摘要: Literature reports several future portable and distributed power supplies in the watt to kilowatt range based on rotating machinery equipped with a variable-speed permanentmagnet generator. In order generate constant dc voltage, an ultra-compact, highly efficient, low rectifier is required. this paper, different topologies are compared concerning losses, volume control complexity. The most suitable, half controlled three-phase PWM boost (HCBR) selected evaluated, novel modulation scheme enhancing electronics efficiency proposed. integration into compressed-air-to-electric-power-system generator at 350 000 rpm presented including measurement results.
