What is cross regulation in flyback converters?

Cross regulation has been a serious limitation in using Flyback converters with multiple outputs. This paper shows a simple technique which minimizes the problem by adding small external inductors. These inductors are used to control the rate at which the secondary current will change when the switch turns off.

What is cross regulation?

Cross regulation is a technique for providing multiple regulated output voltages from an energystorage dc-to-dc converter where only one of the outputs is actually sensed by the controller and regulated to the desired value.

What is the purpose of a flyback converter?

A flyback converter is a simple switch-mode power supply. Flybacks can be used to generate a DC output from either an AC or DC input. Flybacks are designed in such a way that the power from the input is transferred to the output during the off-time of the primary switch.

What is cross regulation in power supply?

Cross regulation: When a power supply has more than one output, changes in the load for one output cause changes in voltage for the other outputs. To determine cross regulation, you divide the voltage change by its nominal value.

What are the advantages and disadvantages of flyback converter?

Important advantage of Flyback converter is the reduced switch/passive element count. In addition, Flyback converter offers higher voltage gain. Following are the disadvantages of application of Flyback converter: Flyback converter require additional snubber circuit to overcome leakage current of inductor.

What are the advantages of forward converter over flyback converter?

The forward converter does have the advantage over the flyback converter when high output currents are required. Since the output current is non-pulsating, it is well suited for applications where the current is in excess of 15A.

What are the advantages of flyback converter?

Advantages of flyback converter The primary is isolated from the output. Capable of supplying multiple output voltages, all isolated from the primary. Ability to regulate the multiple output voltages with a single control. The Flyback converters use very few components compared to the other types of SMPSs.
