The Use of IGBT in Inverter Power Circuits?

Welcome to our channel! In this video, we delve into the fascinating world of power electronics and explore how Insulated Gate Bipolar Transistors (IGBTs) are crucial in improving power factor in inverter circuits. The power factor is a vital parameter that measures the efficiency of electrical systems. Inverter Electric circuits, commonly used in various applications like renewable energy systems and motor drives, can benefit greatly from optimizing power factors. That's where IGBTs come into play! Join us as we explain the fundamentals of IGBTs and their impact on power factor improvement. We'll explore how these advanced semiconductor devices enhance the efficiency and performance of inverter circuits by minimizing reactive power losses and maximizing active power utilization. Throughout the video, we'll break down the working principles of IGBTs, highlighting their ability to switch high voltages and currents with minimal losses. We'll also discuss the benefits of using IGBTs in inverter circuits, such as reduced harmonic distortion and improved overall power quality. Additionally, we'll provide practical tips and insights on incorporating IGBTs effectively in your inverter circuit designs. Whether you're an electronics enthusiast, a student, or a professional in the field, this video will equip you with valuable knowledge to optimize power factors and enhance the performance of your inverter circuits.

Thank you so much, before this video i did not know what those components are for, now i know.

Thank you very much for sharing...God bless.

This means, with two IGBT the current from the capacitor directly behind the bridge rectifier is more equal and at the output there will be less ripple voltage.
On PC motherboards this technique is used too, they use a slight phase shift on every step down converter, so that the step-down converter do not want to get the current to the same time. Maybe every step-down converter activates the MosFET with a time gap of lambda/4.

Firstly, I would like to say that I love your videos, I watch them all and always like them, and I had just fixed a Fujitso that had a communication error, the defect was in the IC ULN2003, but I have a doubt: I thought that the reactor was used to prevent the capacitors from charging too quickly, increasing the initial current too much, which could cause damage to the board or even in the rectifier bridge, since a coil does not accept a rapid variation of current, it would prevent the capacitor from charging quickly. Washing machine has a coil in series with the motor starting capacitor and I believe the purpose is to prevent the capacitor from charging quickly.

Thanks, how can i replace ic pfc oscillator if it burn ?

It's possible to bypass the PFC circuit if IGBT and driver IC are damaged? Often expecially in Inverter Aircon boards this IGBT fail but the power is so low (less than 1kW) so this circuit is basically useless and probably used only for EM compatibility.
