How to Make 250W Inverter using IRF4410


Inverters are devices that convert DC power to AC power and are used to power electrical appliances and equipment in homes and industries. Inverters are common in areas where there is no access to public electricity or as backup power in case of a power outage. In this article, we will explore how to make a 250W inverter that converts 12V DC to 220V AC using the IRF4410 and SG3525 IC.

SG3525 IC: The SG3525 is a pulse width modulation (PWM) controller integrated circuit (IC) capable of producing high-frequency switching signals for power inverters, motor drivers, and other voltage-controlled applications. The IC features a programmable oscillator, a reference voltage generator, error amplifier, pulse width modulator, and output drivers that can be configured to generate single or multiple PWM signals. The SG3525 operates with an input voltage range from 8V to 35V, and it can provide output signals of up to 30V or +/- 15V dual power supply.

IRF4410 MOSFET: The IRF4410 is a high-performance power MOSFET designed for applications such as DC-DC converters, motor control, and power switching circuits. The device features a low on-state resistance of 13 milliohms, allowing high current to pass through with minimal losses. It also has a high voltage rating of 100V, making it suitable for high-power applications. The IRF4410 has a low gate charge, which makes it easy to drive in high-frequency switching circuits. Its TO-220 package allows for easy mounting onto a heatsink for improved thermal performance. The IRF4410 is an N-Channel MOSFET that can handle currents of up to 97A and dissipate up to 250W.
