Circuit/System Description

The accessory DC/AC power inverter module converts 12 V direct current (DC) battery voltage to AC in order to operate AC powered devices. The accessory DC/AC power inverter module is connected to a chassis ground circuit and receives fuse protected battery voltage.

The accessory power receptacle has an internal switch, that detects when an AC powered device is plugged into the receptacle. When the ignition is ON and an AC powered device is plugged into the accessory power receptacle, the normally open switch in the accessory power receptacle, closes. When the accessory DC/AC power inverter module detects the voltage from the accessory power receptacle switch, the inverter module begins to supply AC to the accessory power receptacle after a 1.5 s delay.
