PWM inverter circuit based on SG3524
A 250W PWM inverter circuit built around IC SG3524 is shown here. SG3524 is an integrated switching regulator circuit that has all essential circuitry required for making a switching
PWM (Pulse Width Modulation) signal-based inverters produce output as a pure sine wave and it can be used for any electric appliance that meets the inverter output range. Here we design a simple and powerful PWM inverter circuit by using IC SG3524 (Regulating Pulse Width Modulator) that gives up to 230V AC from a 12V DC supply. 1. 2. 3. 4. 5. 6. 7.
The SG3524 provides the necessary control signals to regulate the output voltage and frequency of the inverter. The circuit diagram for an SG3524 inverter typically includes the SG3524 IC, a few passive components such as resistors and capacitors, power transistors or MOSFETs, transformer, and a feedback circuit.
SG3524 Integrated Circuit (IC): The heart of the inverter circuit is the SG3524 IC. This integrated circuit is a pulse width modulation (PWM) controller that generates the necessary control signals for the transistor switches in the inverter circuit. It provides precise control of the output waveform's frequency and voltage. 2.
These components work together to convert DC power to AC power efficiently and reliably. The SG3524 is a popular integrated circuit that is commonly used in inverter circuits. It is a versatile chip that can be used in a variety of applications, including sine wave inverters.
