What is a power inverter?
A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.
What is a PWM inverter?
Pulse Width Modulated (PWM) inverter bridges and square wave or modified square wave systems that feed a ferroresonant constant voltage transformer. Power transistors (IGBT’s) switch the DC into AC. The battery provides a steady, constant source of power separate from the fluctuations that can be seen on grid power. Why are inverters needed?
How do inverters work?
An inverter takes DC power, such as a battery, and switches the DC off and on to create AC power. There are two major technologies that perform this function. Pulse Width Modulated (PWM) inverter bridges and square wave or modified square wave systems that feed a ferroresonant constant voltage transformer.
What is the AC output frequency of a power inverter?
The AC output frequency of a power inverter device is usually the same as standard power line frequency, 50 or 60 hertz. The exception is in designs for motor driving, where a variable frequency results in a variable speed control.
Do static inverters use moving parts?
Static inverters do not use moving parts in the conversion process. Power inverters are primarily used in electrical power applications where high currents and voltages are present; circuits that perform the same function for electronic signals, which usually have very low currents and voltages, are called oscillators.
What is the input voltage for a power inverter?
The input voltage depends on the design and purpose of the inverter. Examples include: 12 V DC, for smaller consumer and commercial inverters that typically run from a rechargeable 12 V lead acid battery or automotive electrical outlet. 24, 36, and 48 V DC, which are common standards for home energy systems.
