Abstract
A controller for controlling a power converter is described. The controller may include a current sensor and a pulse modulation device. The current sensor may receive a first amount of current from the power converter. In response to receiving the first amount of current, the pulse modulation device may output a pulse modulated signal defined by a first frequency. After outputting the pulse modulated signal defined by the first frequency, the pulse modulation device may adjust the pulse modulated signal from the first frequency to a second frequency. The current sensor may receive a second amount of current from the power converter. The pulse modulation device may also re-adjust, the pulse modulated signal from the second frequency to a third frequency; and output the pulse modulated signal defined by the third frequency.
