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.
