The first one consists in the usage of several power stage capacitors connected in parallel, forming a capacitance sum, witch is determining the output current or power. In this way an easier and more accurate digital control over the output parameters is achieved. Another improvement technique consists in the usage of several power stages, connected in parallel. In this way the output pulsations are much less. A practical solution circuit is designed to illustrate the improvement techniques.

In many areas, such as communication, medicine and military equipments, the high power laser diodes find many applications. In the same time there isn’t a lot of literature about their driving. In this paper some driving circuits and algorithms are discussed. The driving circuits are based on the forward d 2 dc/dc converter. They are designed as power sources with current and voltage limitations. The discussed driving algorithms are based on the one-cycle control. Regulation of this type offers high accuracy and high speed reaction.
