Claim:
1. A power system comprising: a DC power source having a maximum output voltage; a DC/AC inverter having an input coupled via a connection to the DC power source and an output for supplying AC power to a load; and a control circuit for controlling the DC/AC inverter, the control circuit configured to maintain a DC voltage at the input of the DC/AC inverter above a threshold voltage by controlling an amount of current drawn by the DC/AC inverter from the DC power source to inhibit arcing as a result of a break in the connection between the DC power source and the DC/AC inverter; wherein the threshold voltage is substantially equal to the maximum output voltage of the DC power source less a minimum arcing voltage for the connection between the DC power source and the DC/AC inverter.
