摘要
A converter unit configured to couple to a photovoltaic panel may include a controller that monitors: an output voltage and output current obtained from the photovoltaic panel by a switching power core within the converter unit, and an output voltage and output current produced by the switching power core. The controller may calculate a desired duty-cycle value based on the monitored values, and implement a mapping algorithm that translates the duty-cycle value to a pulse-width value and a modulus value. The pulse-width value and the modulus value may be used to simultaneously respectively modulate the pulse-width and pulse-period of a pulse-width modulated (PWM) signal, while maintaining an appropriate linear final duty-cycle ratio between the pulse-width and the pulse-period of the PWM signal. The PWM signal may be provided to the switching power core to control the switching of the switching power core.
