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.
