Power Source - Whistler HIGH SURGE POWER INVERTERS Owner's Manual

radiators or other sources of heat. Do not place the
inverter in direct sunlight.
• VENTILATION. In order to disperse the heat generated
while the inverter is in operation, keep it well ventilated.
While in use, maintain several inches of clearance around
the top and sides of the inverter.
• FUMES & GASES. Avoid using the inverter near
flammable materials. Do not place the inverter in
areas such as battery compartments, where fumes or
gases may accumulate.

1. Basic Operating Principles:
Whistler inverters work in two stages. During the first stage,
the DC to DC converter increases the DC input voltage from
the power source (e.g. a 12 volt battery) to 145 volts DC. In
the second stage, the high voltage DC is converted to 110
volts (60 Hz AC) using advanced power MOSFET transistors
in a full bridge configuration. The result is excellent overload
capability and the capacity to operate difficult reactive loads.
The output waveform resulting from these conversions is a
"quasi-sine wave" or a "modified sine wave" as shown on
the following page.
This stepped waveform is similar to the power generated by
utilities and has a broad range of applications.
