This paper presents the analysis and the design of a peak-current-controlled high-power-factor boost rectifier, with slope compensation, operating at constant frequency. The input current shaping is achieved, with continuous ...

A constant-current stimulator for high-impedance loads using only low-cost standard high-voltage components Is presented. A voltage-regulator powers an oscillator built across the primary of a step-up transformer whose ...

The development and testing of a current comparator (CC) is described. It is intended for ac low frequency applications, such as calibration of instrument current transformers (CT). The CC can be self-calibrated comparing ...
