The proposal of this peak current control in the buck converter topology is performed with the high side current sensing technique to provide overcurrent protection. This overcurrent protection is performed by creating an over current alert whenever there arise an increase in the load current of 1A...
As an active approach to improve the stability degraded by the source subsystem interaction, the positive feedforward (PFF) control is proposed for the peak-current-mode-controlled buck converter. PFF control stabilizes the input port in the frequency range where the source subsystem interaction ...
This paper presents an emulated peak current-mode control topology targeted for a high voltage buck converter for automotive applications, where one of the key challenges is to protect the devices from the high voltage stress. The proposed controller scheme eliminates the issue of the voltage stress...
