Application of Digital Slope Compensation in Peak Current Mode Control of Buck- Boost Converter

Nikhila N,A. Rajalakshmi

Peak current mode control of a buckboost converter along with the load and transient analysis using a PIC microcontroller is done. The new elucidation includes a discrete time controller using digital slope compensation technique which removes all the subharmonic oscillations using a discrete staircase ramp. Combining a digital controller with peak current control gives a number of benefits which is implemented by a new single chip solution with on chip comparators without any external analog ICs. Digital slope compensation is implemented within the PIC controller as a digital staircase ramp using the on board modules.
