Controller for buck dc/dc converter with effective decoupling

controller of a buck DC-DC power converter, the controller comprising:

• a pulse width modulator (PWM) configured to be controlled by a control signal to control at least one switch that is coupled to a buck inductor to allow the buck inductor to operate on a current flowing from a DC link only when the at least one switch is turned ON, the control signal being based on both a measured load current and a measured input voltage, wherein the measured load current is a measurement of current that flows from the buck inductor and the measured input voltage is a measurement of a DC link input voltage measured across the DC link.

A method of controlling a buck DC-DC power converter, the method comprising:

• generating a control signal to control a pulse width modulator (PWM), wherein the control signal is based on both a measured load current and a measured input voltage, wherein the measured load current is a measurement of current that flows from a buck inductor of the buck DC-DC power converter and the measured input voltage is a measurement of a DC link input voltage measured across a DC link of the buck DC-DC power converter;
• and
• controlling by the PWM at least one switch that is coupled to the buck inductor to allow the buck inductor to operate on a current flowing from the DC link only when the at least one switch is turned ON.
