Abstract :
A novel large-signal control algorithm for buck-type derived power processing cells has been proposed. It is efficient in protecting the power switch during the turn-on and short-circuit transients and features an inherent feedforward of the input voltage. The implementation of the proposed algorithm can be realized by a very simple analog processor comprising only summing networks and comparators and could be done by means of a single dedicated integrated circuit. Beside being protected during the transients, the cells where this algorithm is implemented are insensitive to input filters; thus, simple and robust filters can be used at the input to ameliorate the waveshape of the absorbed current and the power factor of the installation. The theoretical background is confirmed by computer simulation and both are shown to agree with the measurements performed on a 380 V input 6 kW battery charger
