How This Inverter Works
This inverter is an electronic device that converts low voltage DC (direct
current) electricity from a battery to 120 volts AC (alternating current)
household power. It 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 a MOSFET bridge
stage that converts the high voltage DC into 120 volts, 60 Hz AC.
Power Inverter Output Waveform
The AC output waveform of this inverter is known as a modified sine
wave. It is a stepped waveform that has characteristics similar to the
sine wave shape of utility power. This type of waveform is suitable for
most AC loads, including linear and switching power supplies used in
electronic equipment, transformers, and small motors.
Rated Versus Actual Current Draw of
Equipment
Most electrical tools, appliances, electronic devices and audio/visual
equipment have labels that indicate the power consumption in amps or
watts. Be sure that the power consumption of the item to be operated
is below 1000 watts. If the power consumption is rated in amps AC,
simply multiply by the AC volts (120) to determine the wattage.
Resistive loads are the easiest for the inverter to run; however, it will
not run larger resistive loads (such as electric stoves and heaters),
which require far more wattage than the inverter can deliver. Inductive
loads (such as TVs and stereos) require more current to operate than
do resistive loads of the same wattage rating.
WARNING: If the product does not operate normally, to
reduce the risk of injury or property damage, turn the product
off immediately and unplug it from the inverter.
CAUTION
– To reduce the risk of injury: Do NOT touch the metal
part of the DC plug after use as its surface may be quite hot after
extensive operation.
