Traditionally, dc-ac inverters (also known as static inverters) use fixed dc sources to produce symmetrical ac output voltages at fixed or variable frequency or magnitude. The output ac voltage system can be of the single-phase or three-phase type at frequencies of 50, 60, and 400 Hz with a voltage magnitude range of 110 − 380 VAC.
The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control. The inverter outputs a pulsed voltage, and the pulses are smoothed by the motor coil so that a sine wave current flows to the motor to control the speed and torque of the motor.
For example, an inverter used to provide necessary changes in the frequency of the ac output is used to regulate the speed of an induction motor and is also used in a UPS system to produce a fixed ac frequency output when the main power grid system is out.
An inverter uses this feature to freely control the speed and torque of a motor. This type of control, in which the frequency and voltage are freely set, is called pulse width modulation, or PWM. The inverter first converts the input AC power to DC power and again creates AC power from the converted DC power using PWM control.
Each inverter/charger contains an internal AC input contactor. These contactors are not always completely identical, they can have a small difference in their internal resistance, compared to the other contactors. This small resistance difference might result in the AC current being diverted from one unit to another.
Medium- and high-power half-bridge and full-bridge switching devices using MOSFETs, IGBTs, and SiC- and GaN-based-devices are available as packages. Dc-ac inverters are used in applications where the only source available is a fixed dc source and the system requires an ac load such as in uninterruptible power supply (UPS).
