Abstract

For more industrial application, need to change of constant DC Voltage to variable DC Voltage, or otherwise. DC Chopper change directly from DC to DC which is called as DC to DC Converter. Like a transformer, the Chopper can used to step down or to step up DC Voltage source. The DC power source or DC generator basicly will supply the energy to DC load. If Voltage from generator or source largest than load, so its need to add DC to DC Converter so that the Voltage can be stable and be supplied to load. Buck Converter be used to step down Voltage source if it overshoot against set point. The Mosfet switching in DC to DC circuits be controlled by PWM (Pulse Width Modulation) with Closed Loop Control System method.
