7. eta Works An inverter is an electronic device that converts low voltage DC direct current electricity from a battery or other power source to the standard 240 volts AC alternating current household power In designing the Theta SC Origin has used design techniques previously employed in computer power supplies to give you an inverter that is smaller lighter and easier to use than any other inverter with a similar power rating Principle of operation The Theta converts power in two stages The first stage is a DC to DC converter that raises the low voltage DC at the inverter input to 240 volts DC The second stage is the actual inverter stage It converts the high voltage DC into 240 volts 60 Hz or 50 Hz AC The DC to DC converter stage uses modern high frequency power conversion techniques that makes the bulky transformers found in inverters based on older technology obsolete The inverter stage uses advanced power MOSFET transistors in a full bridge configuration This gives you excellent overload capability and the ability to operate tough reactive loads like lamp ballasts and small induction motors Theta Modified Sine Wave output waveform The AC output waveform of the Theta is called a quasi sine wave or a modified sine wave It is a stepped waveform that is designed to have characteristics similar to the 3 sine wave shape of utility power A waveform of this type is suitable for most AC loads including linear and switching p
