The basic idea is to deliver a series of constant-amplitude, variable-width pulses of voltage to the load to simulate a sinusoidal voltage of the desired frequency. The inductance of the motor keeps the current flowing between the pulses, resulting in an almost sinusoidal current. There are a variety of control schemes for PWM inverters.
Some of the circuits used in the PWM inverter are explained below. Battery charging current sensor circuit. This circuit senses the charging current of the battery in order to keep the charging current with in the rated value.A charging current lower or higher than the allowed range can reduce battery life. Battery voltage sensing circuit.
There are a variety of control schemes for PWM inverters. Figure 1 shows the principles of sinusoidal modulation, which uses a reference signal and a modulation signal. The reference signal is the desired sinusoidal voltage of the appropriate frequency. The reference signal is a triangular waveform operating at a carrier frequency.
Single-phase PWM inverters consist of two main parts, the DC power source and the inverter bridge, typically use a full-bridge configuration consisting of four power switches, usually IGBTs and MOSFETs. The switches are controlled in pairs, with diagonal pairs operation together.
