چکیده
AbstmctThis paper presents a feedforward ripple cancellation technique for use with a full-bridge DC-DC converter. The full-bridge is used to energize an inductive coupling that serves as an isolating connector in a battery charging system. Feedforward ripple cancellation prevents large ac currents from flowing into the battery terminals in response to unavoidable ac ripple on the inverter input bus voltage. A computationally inexpensive technique for implementing ripple cancellation using either analog or digital hardware is described and demonstrated on a 1500 watt hardware prototype.

A Topology Survey of Single-Stage Power Factor Corrector with a Boost Type Input-Current-Shaper - Applied Power Electronics Conference and Exposition, 2000. APEC 2000. Fifteenth Annual IEEE
A topological review of the single stage power factor correctted (PFC) rectifiers is presented in this paper. Most of reported single-stage PFC rectifiers cascade a boosttype converter with a forward or a flyback dc-dc converter so that input current shaping, isolation, and fast output voltage regulation are performed in one single stage. The cost and performance of a single-stage PFC converter...

This paper describes the design of a high speed semiconductor laser diode driver designed for driving 500 mW to 1.5 W diodes at full optical power modulation up to frequencies of 10 MHz. The duty cycle of the modulation may be varied. A switching power-converter based current source allows a higher power delivery efficiency to the diode than in previous designs, allowing for a more modest power...
