HOW THIS INVERTER WORKS

This inverter is an electronic device that converts low voltage DC (direct current) electricity from a battery

to 115 volts AC (alternating current) household power. In designing this inverter, Black & Decker has

incorporated design techniques previously employed in computer power supplies. The result of these

design innovations is a smaller, lighter and easier-to-use power inverter.

The Power 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 a MOSFET bridge

stage that converts the high voltage DC into 115 volts, 60 Hz AC.

The DC-to-DC converter stage uses creative, high frequency, zero voltage switching power conversion

techniques that replace the bulky transformers found in less technologically advanced models. The

inverter stage uses advanced power MOSFET transistors in a full bridge configuration.

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.

The modified sine wave produced by this inverter has an RMS (root mean square) voltage of 115 volts.

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 correctly read the RMS voltage of a modified

sine wave. Non-TRUE RMS meters will read about 20 to 30 volts low when measuring the output of this

inverter. For accurate measurement of the output voltage of this unit, use a TRUE RMS reading voltmeter

such as a Fluke 87, Fluke 8080A, Beckman 4410 or Triplett 4200.

CAUTION

Rechargeable Devices

• Certain rechargeable devices are designed to be charged by plugging them directly into an AC receptacle.

These devices may damage the inverter or the charging circuit.

• When using a rechargeable device, monitor its temperature for the initial ten minutes of use to determine

if it produces excessive heat.

• If excessive heat is produced, this indicates the device should not be used with this inverter.

• This problem does not occur with most of the battery-operated equipment. Most of these devices use a

separate charger or transformer that is plugged into an AC receptacle.

• The inverter is capable of running most chargers and transformers.

Soft Start Technology

Black & Decker's Soft Start Technology gradually "ramps up" the inverters power to slowly start

appliances that require a surge to get started. This gradual ramp up protects the inverter and the

appliance, as well as the power source, from damage and failure.
