How does a general-purpose inverter work?
The voltage output from the inverter is in pulse form. The pulses are smoothed by the motor coil, and a sine wave current flows. As a result, the output from a general-purpose inverter cannot be used for equipment other than motors.
What does a high efficiency inverter mean?
A: The efficiency of the inverter is a measure of how much of the input power is converted into output power. A higher efficiency means that more of the input power is used to generate output power, and this will result in a higher output voltage from the inverter.
How does an inverter work?
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.
