Quasi Resonant Flyback Design Tool – Automated and Hassle Free

Are planning to design your own QR flyback? This Quasi Resonant Flyback Design Tool will help you do the job effortlessly. All you need to do is to download the tool on the lowest part of this page. Also ensure that you have Mathcad 14 on your PC to open the file. Try search online if lower versions or higher versions of Mathcad can read Mathcad 14 if you don’t have the 14 version. Below are the top-level explanations to every step on this quasi resonant flyback design tool

Quasi Resonant Flyback Operation Checker and Design Tool – Excel

The operation of a quasi resonant converter is dependent to the primary inductance of the transformer, stray capacitance of the circuit (mostly on the primary switch), reflected voltage to the primary winding during flyback action, turns ratio of the transformer, and the given voltages like input voltage, output voltage, output power and intended frequency of operation. For a beginner or not technical person, these are too much to handle. It will take time even for a technician or an inexperienced engineer to digest all these. However, you don’t need to extend extra effort anymore. There is already a Quasi resonant flyback operation checker and design tool available.

NPN Fixed Bias Design Template

This circuit configuration of NPN transistor is very useful in electronic switch. It has a guaranteed logic high or low when biased properly. This circuit also is can be used in linear operations or amplifier mode by changing the biasing.
