Today we are going to look into a very high efficiency resonant-mode off-line LED driver circuit. It is based on a very popular Infineon article which uses the IRS2530D DIM8 controller IC. Normally electronic ballast technology is used for old fluorescent tube lights, but here Infineon used the same concept to drive high power LEDs […]
SMPS and Converters
Adjustable 1Amp to 10Amp, 3V to 14V SMPS Circuit: CV, CC, and Short Circuit Protected
If you have ever tried building a high-power inverter, a high-frequency induction heater, or just a solid adjustable lab bench power supply, you already know that controlling both the voltage and current at the same time is an absolute nightmare. Most builders just grab the standard application circuit from the SG3525 datasheet, wire up a […]
How to Add Adjustable Current and Voltage feedback Control to SG3525 High Power Inverters
If you want to build a very heavy power inverter or when you want to make a high frequency induction heater, or when you want to make a lab grade variable SMPS, then getting precise control over both output voltage and current is a major engineering hurdle. Most standard designs using the classic SG3525 PWM […]
Ferrite Core Air Gap Calculator Tool
You can use this calculator in your workshop or while designing an SMPS prototype, to find the exact physical gap required between your ferrite core pieces to hit your target inductance. Flyback Transformer Air Gap Calculator Flyback Transformer Air Gap Calculator Target Primary Inductance (Lp in µH): Primary Winding Turns (Np): Core Cross-Section Area (Ae […]
Build Customized 220V Flyback SMPS Circuits: 12V, 5A, 60W Example Discussed
In this post I will explain you all the simple formulas, step by step, which you can use for designing and building professional grade 220V AC SMPS flyback converter circuits. As we know the SMPS transformer is the heart of an SMPS design, so here we will learn all the steps, one by step, using […]
Difference Between Forward Converter and Flyback Converter
We know SMPS can be made in different ways, but two common ones are flyback converter and forward converter, which may look same at first. But inside working is not same at all, so this part matters before you design transformer or power stage. Audio/Video Representation Flyback Converter We see a flyback converter works in […]
