资料介绍

Experienced SwitchMode Power Supply designers

know that SMPS success or failure depends heavily

on the proper design and implementation of the

magnetic components. Parasitic elements inherent in

high frequency transformers or inductors cause a variety

of circuit problems including: high losses, high

voltage spikes necessitating snubbers or clamps, poor

cross regulation between multiple outputs, noise coupling

to input or output, restricted duty cycle range,

etc. Figure I represents a simplified equivalent circuit

of a two-output forward converter power transformer,

showing leakage inductances, core characteristics

including mutual inductance, dc hysteresis and saturation,

core eddy current loss resistance, and winding

distributed capacitance, all of which affect SMPS

performance.
