Abstract: A power system that increases the power capability of a DC/AC converter includes a processor coupled to the DC/AC converter and a memory subsystem coupled to the processor. The memory subsystem stores code that when executed by the processor instructs the processor to perform a number of steps. The processor determines when an electrical load that is coupled to the DC/AC converter causes a link voltage of the DC/AC converter to fall below a first predetermined link voltage level. The processor then controls a DC/AC output inverter of the DC/AC converter to cause the DC/AC converter to provide a non-sinusoidal output waveform. The processor also controls the DC/AC output inverter to cause the DC/AC converter to provide a sinusoidal output waveform, when the link voltage exceeds the first predetermined link voltage level or a second predetermined link voltage level.

Abstract: A power system for increasing a load start-up capability of a DC/AC converter includes a DC/AC converter, a processor coupled to the DC/AC converter and a memory subsystem coupled to the processor. The memory subsystem stores code that when executed by the processor instructs the processor to perform a number of steps. When an actual link voltage of a DC/AC converter falls below a predetermined link voltage level, when a commanded link voltage is set for a nominal link voltage level, the commanded link voltage is increased to link voltage level that is greater than the nominal link voltage level. The DC/AC converter is then restarted.
