In this paper, a control strategy is presented for the power supplies with pulsed current load. In these power supplies, a decrease in output voltage of the power supply is expected when the pulsed current is applied. In this situation, There is a great difference between the peak and the RMS value of the inverter output current which results in a nonoptimal design for keeping the inverter switches safe which is not suitable in many applications. In this paper, a control method is presented which has the ability of improving the peak current stress in the inverter without disadvantages of the conventional method.This method is implemented and up to 65% decrease in the peak switch current stress has been observed. The effect of using such a method on improving the inverter current stress is verified in experimental tests.
