4-1 Section 4 Power Transformer DesignPower Transformer DesignThis Section covers the Design of Power trans-formers used in buck-derived topologies: forwardconverter, bridge, half-bridge, and full-wave center-tap. Flyback transformers (actually coupled induc-tors) are covered in a later Section . For more spe-cialized applications, the principles discussed hereinwill generally of a TransformerThe purpose of a Power Transformer in Switch-Mode Power Supplies is to transfer Power efficientlyand instantaneously from an external electrical sourceto an external load. In doing so, the Transformer alsoprovides important additional capabilities: The primary to secondary turns ratio can be es-tablished to efficiently accommodate widely dif-ferent input/output voltage levels. Multiple secondaries with different numbers ofturns can be used to achieve multiple outputs atdifferent voltage levels.
causes voltage spikes during switching transitions resulting in EMI and damage or destruction of switches and rectifiers. Protective snubbers and ... and well distributed by making the rms current den-sity approximately equal in all windings. With a bridge or half-bridge primary, which has good wind- ...
