12 Facts About Power inverter

Power inverter, inverter or invertor is a power electronic device or circuitry that changes direct current to alternating current .

AC output frequency of a power inverter device is usually the same as standard power line frequency, 50 or 60 hertz.

AC output voltage of a power inverter is often regulated to be the same as the grid line voltage, typically 120 or 240 VAC at the distribution level, even when there are changes in the load that the inverter is driving.

Not all inverter applications are solely or primarily concerned with power delivery; in some cases the frequency andor waveform properties are used by the follow-on circuit or device.

Runtime of an inverter powered by batteries is dependent on the battery power and the amount of power being drawn from the inverter at a given time.

An Power inverter can be used to control the speed of the compressor motor to drive variable refrigerant flow in a refrigeration or air conditioning system to regulate system performance.

Traditional methods of refrigeration regulation use single-speed compressors switched on and off periodically; Power inverter-equipped systems have a variable-frequency drive that control the speed of the motor and thus the compressor and cooling output.

Solar Power inverter is a balance of system component of a photovoltaic system and can be used for both grid-connected and off-grid systems.

In other applications, a conventional Power inverter can be combined with a battery bank maintained by a solar charge controller.

The Power inverter must be synchronized with grid frequency and phase and minimize harmonic generation.

Switch in the simple inverter described above, when not coupled to an output transformer, produces a square voltage waveform due to its simple off and on nature as opposed to the sinusoidal waveform that is the usual waveform of an AC power supply.

The Power inverter SCRs are switched in a six-step sequence to direct the current to a three-phase AC load as a stepped current waveform.
