Abstract

A new voltage control method is proposed for dc to ac inverter-plus-LC-filter subsystems of micro-energy electrical supply units that are connected to stand-alone loads or to the utility system. The proposed method is developed from different voltage control methods published in literature. The method uses among other things higher order compensation loops. An advantage is that only output voltages are measured. Simulated performance results are presented of a 400 kVA inverter supply subsystem. Good correlation is obtained between measured and simulated results of an 8 kVA laboratory supply system
