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.
A power inverter is an electronic device that converts direct current (DC) to alternating current (AC) to power appliances and devices that require AC power. A pure sine wave inverter produces a smooth and clean AC output that closely resembles the waveform of grid electricity.
The pure sine wave inverter circuit diagram using SG3525 consists of several basic components, including the SG3525 IC itself, a power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor), a step-up transformer, a filter capacitor, and an output socket. The SG3525 IC receives a DC input voltage and generates a PWM signal.
The "chopping" is done by feeding a calculated PWM to the gates of the FET via a BJT buffer stage. A typical circuit design for converting the SG3525 waveform into a pure sine wave waveform is shown below. This design is actually an universal design which may be implemented for upgrading all square wave inverters into sine wave inverters.
