Development of an FPGA-based Adaptable Peak Current-Mode Control for Use in Green Energy Conversion

摘要: An adaptable peak current-mode control (APCMC) was developed for a buck converter. This APCMC implemented using field programmable gate array (FPGA) and has applications in green energy conversion. FPGA chosen to implement the as it inherent capability multitasking adding functionality without changing hardware. The number of parts minimized only requires an FPGA, power timing circuitry, comparator, single-pole RC filter. Instead compensating ramp with constant slope is used conventional control, uses curve that varying optimized each value duty cycle. such will not prevent sub harmonic oscillations, but also enable deadbeat response at all values derived from model modified z-transforms.
