PULSE WIDTH MODULATION POWER CONVERTER AND CONTROL METHOD

摘要

In a Pulse Width Modulation power converter and control method, wherein one of the operating modes steady state or load transient is detected. For either of the two operating modes one set of PID coefficients is provided for the control law that controls the duty ratio command. In case a load transient is detected, the KP gain is selected adaptively. Operating mode detection is supported by oversampling the error signal.
