<p>An alternator/inverter system for use with a portable generator, which includes a voltage regulation system. The alternator/inverter incorporates a pair of permanent magnet generators “PMGs” (16, 40), a pair of active rectifier circuits (18, 42), a pair of DC bus capacitors (38, 48) and a pair of H-bridge inverters (24, 50), forming two distinct alternator/inverter sections (12, 14). Each alternator/inverter section provides a 120 VAC output (64, 66), and a 240 VAC output (68) is formed between the two alternator/inverters sections. The voltage regulation system is formed from a pair of voltage regulation circuits that are associated with each alternator/inverter section. The circuits monitor the DC bus voltage of each alternator/inverter and determine the DC losses resulting from electrical cabling coupling the alternator/inverters to external loads, as well as the H-bridge inverters. A microcomputer (72) or an analog device(s) controls the rectifiers of each to perform 'V+IR' compensation based on the sensed DC bus voltage of each alternator/inverter section.</p> |
