Abstract :
The use of high-frequency PWM converters for laser diodes operating in a pulse mode is a prospective direction. High demands are made to the quality of pump current pulses. In this paper the dual-channel step-down DC/DC converter is considered as a pulse shaper. In addition, the converter control method is proposed. This method allows to set phases of the control signals quickly and without changing the common output current. To show the applicability of this method the PSIM model was developed.
