Improvement in transient upload response of boost converter using input inductor current injection based on FPGA digital control

In this paper, an input inductor current injection technique, together with the one-comparator counter-based pulse-width-modulation (PWM) control strategy, is presented herein and applied to the boost converter to upgrade its stability and transient upload response. This is easy to realize based on the field programmable gate arrays (FPGA). The detailed illustration of the proposed control strategy is provided, along with some experimental results.
