Quasi Resonant Flyback Waveform

How Quasi Resonant Flyback Works – Detailed Operation

A quasi resonant flyback converter is a variant of flyback converter wherein it makes use of the parasitic elements to partially resemble a resonance action. According to dictionary, the word quasi could mean partly, partially, comparatively or relatively. So, a quasi-resonance means a partial resonance, not a total resonance. At light load, Quasi resonant flyback operation will be in DCM. However, it will come closer to the boundary or transition mode while in full load.

How Flyback Converter Works – Operation and Principle

A flyback converter is composed of a flyback transformer, switch, rectifier and filter and the control mechanism to drive the switch and provide regulation. It is a low part count switching converter and relatively easy to make or design. A flyback converter is an isolated switching converter that can be a step down or step up configuration. Most cell phone, tablets and laptop chargers are made from flyback converter. Following topics will discuss how flyback converter works.

How to Know a Defective Diode

Diode is a two terminal semiconductor device. One terminal is called the anode while the other terminal is cathode. Anode needs a high potential while cathode needs a lower potential level for the diode to be forward biased. The term forward biased means the diode terminals are supplied with the right voltage level. When the diode is not supplied by

Power MOSFET Design Equations

here are only few power MOSFET design equations to take note when doing design involving this electronic part. You may try deriving these equations if you want a better understanding on how these formulated. These are also given in application notes and some technical blogs but maybe in different form but will result to the same calculation results.
