An ac voltage supply, after rectification into dc will also qualify as a dc voltage source. A voltage source is called stiff, if the source voltage magnitude does not depend on load connected to it. All voltage source inverters assume stiff voltage supply at the input. Some examples where voltage source inverters are used are: uninterruptible

Technical Explanation for Inverters

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. The voltage output from the inverter is in pulse form. The pulses are smoothed by the motor coil, and a sine wave current flows.
