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.
