ABSTRACT:
A variable-frequency converters with very wide input voltage tolerance using of variable delays which are proportional to the ratio between the input voltage and the output voltage. This variable delay provides good tolerance for variation in V.sub.in, as well as for variation in V.sub.out. This ratio-dependent delay is used by a secondary-side control subsystem to simulate the current on the primary side, without using any dissipative current sensing techniques.
