NCP1612 - Enhanced, High Efficiency Power Factor Controller

The NCP1612 is designed to drive PFC boost stages based on an innovative Current Controlled Frequency Fold−back (CCFF) method. In this mode, the circuit classically operates in Critical conduction Mode (CrM) when the inductor current exceeds a programmable value. When the current is below this preset level, the NCP1612 linearly decays the frequency down to about 20 kHz when the current is null....

Novel DC/DC Converters For High-Power Distributed Power Systems

A Robust Controller For DC-DC Switched Mode Power Converters

Power converters often consist of linear circuits that are switched between two configurations. Even though each of the configurations is linear, the overall behavior of the circuit is nonlinear. DC-DC switched mode power converters constitute simple but yet efficient means of DC power regulation [ 1,2]. The analysis and control of such a circuit is fairly complicated. Different methods have be...
