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), a pair of active rectifier circuits, a pair of DC bus capacitors and a pair of H-bridge inverters, forming two distinct alternator/inverter sections. Each alternator/inverter section provides a 120 VAC output, and a 240 VAC output 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 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.
