Cathodic protection (CP) DC/DC converters are the external power sources used in CP systems to convert fix DC voltage to variable DC output voltage and bring about variable output current as well. In low to medium output voltages, where the duty cycle is less than 30%, zero voltage switching (ZVS) is unattainable. Therefore, a switching control method which is the combination of ZVS and variable frequency pulse width modulation (VFPWM) is proposed in this paper. Using the proposed method, the DC/DC full-bridge converter can operate under a wide range of output voltage from 0 to 75V and output current from 0 to 25A with high efficiency. Simulation results demonstrate the accuracy of this method.
