Product Introduction
The DC flyback transformer is the core magnetic component in flyback DC-DC isolated power supplies, operating at high-frequency switching mode with DC input voltage controlled by the high-frequency on-off action of the switching transistor. Its operating principle is as follows: when the switching transistor is turned on, the primary core stores energy via the air gap; when the switching transistor is turned off, the core releases energy to output DC voltage at the secondary side.
Product Features
The DC flyback transformer features a relatively simple structure, low cost, and easy implementation of multi-channel DC voltage outputs. It also boasts a compact size and high operating efficiency. With a relatively low power rating, the product supports fully automated production.
Application Fields
DC flyback transformers are mainly used in:
FAQ
Q: What is the difference between a high-frequency flyback transformer and a high-frequency forward transformer?
A: A flyback transformer is a gapped coupled inductor for energy storage, while a forward transformer is a conventional transformer for energy transfer only.
A flyback transformer stores energy when on and releases it when off, transferring energy sequentially; a forward transformer transfers energy directly when on and requires core reset.
A flyback transformer uses a simple circuit with no output inductor; a forward transformer has a more complex circuit with an output inductor and reset circuit.
Flyback transformers are ideal for low power, easy multi-outputs and inherent short-circuit protection, but with higher ripple. Forward transformers suit medium-to-high power, offering lower ripple and higher efficiency.
