So here we are trying to understand whether we must put a freewheeling diode directly across the inductor in a boost converter or not, to safeguard the switching transistor? How Boost Converter Works So in a boost converter, we got one inductor, one power switch like a MOSFET, one diode and one output capacitor. Input […]

SG 3525 Automatic PWM Voltage Regulation Circuit
In this post I have explained a simple configuration which can be added with all SG 3525/3524 inverter circuits for implementing automatic PWM output voltage regulation by the IC. The solution was requested by Mr. Felix Anthony. The Circuit Problem: Sir, I would need your help on a project about a schematic that I do […]
USB 5V To 24V DC to DC Boost Power Regulator Module
This is a USB 5V to 24V Adjustable Boost Converter Module and it helps us step up a lower voltage into a higher voltage which we can adjust as needed. Now let us go through everything in detail step by step. Inputs – Where We Give Power Now we got three ways to power this […]
SCR/Triac Controlled Automatic Voltage Stabilizer Circuit
In this article I have explained a relatively simple triac controlled automatic mains voltage stabilizer circuit, which uses logic ICs and a few triacs for controlling the mains voltage levels. Why Solid State Being solid state in design, the voltage switching transitions are very smooth with minimum wear and tear, resulting in efficient voltage stabilization. […]
Designing a Power Factor Correction (PFC) Circuit Using UC3854 – Key Considerations
The IC UC3854, what it does is, it helps in active power factor correction, right? Now normally, if we don’t correct the power factor, then power system will pull current from the AC mains in a way that’s not a nice sine wave but rather distorted. This IC takes care of all the control stuff […]
PWM Controlled Voltage Stabilizer Circuit
In this post I have explained how to make a high power 100V to 220V H-bridge mains voltage stabilizer circuit using automatic PWM control. The idea was requested by Mr. Sajjad. Circuit Objectives and Requirements Secondary Features I like it to has an LCD to display parameters and a custom name,high voltage cut off, over […]
