Abstract
Disclosed is a DC-to-AC power converter (10) that includes a high power DC-to-AC converter (20) and a low power DC-to-AC converter (40). The low power DC-to-AC converter produces a continuous 120-volt AC signal until a load sense circuit (60) determines that a load (14) is drawing more than a predetermined level of power. The load sense circuit then transmits a load sense signal to a control circuit (80) that disables the low power DC-to-AC converter and enables the high power converter. As a result, the DC-to-AC power converter is able to start virtually any load while conserving the power of a DC source.
