Inverter voltage (VI) is an essential concept in electrical engineering, particularly in the design and operation of power electronics systems. It describes the output voltage of an inverter, which converts direct current (DC) from sources like batteries or solar panels into alternating current (AC).
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.
It’s important to note what this means: In order for an inverter to put out the rated amount of power, it will need to have a power input that exceeds the output. For example, an inverter with a rated output power of 5,000 W and a peak efficiency of 95% requires an input power of 5,263 W to operate at full power.
For applications needing smoother AC power, inverters producing pure sine wave alternating current are essential. By adjusting the duty cycle of PWM according to sinusoidal law, inverters generate a waveform resembling a sine wave. SPWM (Sine Wave Pulse Width Modulation) arranges pulse widths and duty cycles to mimic a sinusoidal pattern.
