Abstract :
The designed switch mode power supply source (SMPS) is described. It consists of a net filter, power factor correction (PFC) circuits, pulse width modulation (PWM) controller, driver stage, PWM output stage, output transformer and voltage converter. The PFC principle is described in detail. The PWM output part was designed to deliver output power of the SMPS up to 1200 W. The calculated and the measured parameters of the output pulse transformer and the filter inductor are given. The measured values of the designed SMPS show the efficiency nearly 90% at the half and the maximum output power value.
