WORKING PRINCIPLES
HOW YOUR INVERTER WORKS
The inverter converts low voltage DC (Direct Current) from a Kobalt 80V lithium battery to standard
120 volt AC (Alternating Current) household power.
PRINCIPLE OF OPERATION
The inverter converts power in two stages.
• The rst stage is a DC to DC conversion process that raises the low voltage DC at the inverter input
to high volts DC.
• The second stage is the actual inverter stage that converts the high voltage DC into AC.
NOTE:
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 conguration.
THE OUTPUT WAVEFORM
The AC output waveform of the KIV 3080-06 inverter is known as “modied sine wave”. It is a
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 motors.
The modied sine wave produced by the KIV 3080-06 inverter has an RMS (root mean square)
voltage of 120 volts, which is the same as standard household power. Most AC voltmeters (both digital
and analog) are sensitive to the average value of the waveform rather than the RMS value. They are
calibrated for RMS voltage under the assumption that the waveform measured will be a pure sine
wave. These meters will not read the RMS voltage of a modied sine wave correctly. They will read
about 20 to 30 volts low when measuring the output of the inverter. For accurate measurement of the
output voltage of this unit, use a true RMS reading voltmeter.
