Outlets accommodate either two or three pin AC plugs. An On/Off Switch
turns the inverter circuitry On and Off. The switch is used to force reset of
inverter circuits if it is switched Off, then On.

HOW YOUR VECTOR INVERTER WORKS
The inverter converts low voltage DC (direct current) from a battery or other
power source to standard 110 volt AC (alternating current) household
power.
3.1 PRINCIPLE OF OPERATION
The inverter converts power in two stages. The first stage is a DC-to-DC
conversion process that raises the low voltage DC at the inverter input to
145 volts DC. The second stage is the actual inverter stage that converts the
high voltage DC into 110 volts, 60 Hz AC.
The DC-to-DC converter stage uses modern high frequency power
conversion techniques that have replaced the bulky transformers found in
less technologically-advanced models. The inverter stage uses advanced
power MOSFET transistors in a full bridge configuration. This ensures
excellent overload capability and the ability to operate reactive loads like
lamp ballasts and small induction motors.
