Most inverters rely on resistors, capacitors, transistors, and other circuit devices for converting DC Voltage to AC Voltage. In alternating current, the current changes direction and flows forward and backward. The current whose direction changes periodically is called an alternating current (AC). It has non-zero frequency.
The inverter section is comprised of IGBTs that create sinusoidal output current using pulsed dc bus voltage, or pulse width modulation (PWM). Frequency inverters themselves are sometimes called inverters, as the presence of an inverter section is the primary difference between frequency inverters and dc converters. 4.
The working principle of AC frequency inverters is based on PWM (Pulse Width Modulation) technology. The AC frequency inverter receives AC power from the grid, rectifies it into DC power, and then converts the DC power back into AC power through an inverter.
AC frequency inverter: AC frequency inverter is the most common type, used to control the speed of AC motor. The frequency inverter adjusts the running speed of the motor by changing the input voltage and frequency of the motor.
PWM: A frequency inverter control scheme in which a constant dc voltage is used to reconstruct a pseudo ac voltage waveform using a set of six power switches, usually IGBTs. Varying the width of the fixed-amplitude pulses controls effective voltage.
An inverter that converts a direct current into an alternating current is called a DC-AC inverter. However, the term “inverter” generally refers to the equipment that combines an AC-DC converter (that changes an alternating current into a direct current) and a DC-AC inverter so as to be able to generate arbitrary frequencies and voltages.
