Quasi Resonant Flyback Transformer Saturation Analysis

One of the very important aspect to look at in dealing with quasi resonant flyback transformer is the saturation. A quasi-resonant flyback transformer is not actually a transformer that we usually know. A transformer will transfer energy from the primary to the secondary at real time. However, the flyback converter will store energy on the primary and then transfer that energy to the secondary somehow. This action makes a flyback transformer prone to saturation if not properly been designed.

How to Use MOSFET as Reverse Battery Protection

You may not know how to use MOSFET as reverse battery protection. The most common method is using a diode. However, diode voltage drop is high and this will creat issue in low voltage circuits. That is the reason many use MOSFET as reverse battery protection due to its very low on state voltage drop.

Quasi Resonant Flyback Duty Cycle Derivation

Quasi Resonant flyback duty cycle will reach maximum when it operates in the transition mode or boundary region. However, as long as the operation will stay at the discontinues mode (DCM), that is the desired region of operation, the Quasi resonant flyback duty cycle will be variable.

Quasi Resonant Flyback Operating Modes

Each of the quasi resonant flyback operating modes discussed above has its strength and weaknesses. It is up to the designer to which mode to select. In my personal experience, I already used both the DCM and TM operating modes. Basically, a quasi resonant flyback will operate in DCM at light load and approaches to TM at very heavy load. During the design stage, the designer will set the operating point in first valley switching for heavier loads for optimum performance.
