A Comparative Analysis on Different Control Techniques for Buck Converters

Buck converters are basically step down DC-DC converter which converts high DC input voltage to low DC output voltage. These buck converters are used extensively in industry and in research. One of the basic disadvantages of buck converters is the unregulated supply of voltage and current. To solve this problem various control techniques are used in combination with buck converters. In this paper some of these control techniques are compared summarized. Some of the famous control methods are Voltage Mode Control (VMC), Current Mode Control (CMC), PID control and Pulse width Modulation (PWM) control.
