The input voltage, output voltage, frequency and overall power handling depend on the design of the specific device or circuitry. An Uninterruptible Power Supply (UPS) is a typical example of an DC to AC inverter. It provides an alternate electric power supply for connected electronic equipment when the primary power source is not available.
Voltage control of inverters is employed in order to compensate for changes in input dc voltage. Basically, there are three techniques by which the voltage can be controlled in an inverter. They are, Internal control of Inverter.
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.
Basically, there are three techniques by which the voltage can be controlled in an inverter. They are, Internal control of Inverter. In this method of control, an ac voltage controller is connected at the output of the inverter to obtain the required (controlled) output ac voltage.
The DC-DC will not control the DC BUS voltage but will control the input panel voltage and work in the power output mode. So, the DC-AC part (inverter) is responsible for controlling the DC BUS voltage.
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.
