Boost Converter with Main Switch Possessing ZVT and ZCT and Auxiliary Switch Possessing ZCS

In this paper, a zero-voltage and zero-current transition (ZVZCT) boost converter is presented with small number of auxiliary components, such as resonant capacitor, inductor an power switch, to produce main switch both switching (ZVS) (ZCS). Furthermore, the also has zero current switching. addition, look-up table employed implement auto-tuning technique regulate trigger position turn-on time further improve efficiency, especially at light load, thereby making overall efficiency present horizontal curve. Moreover, in terms system control, digital controller implemented directly from z-domain, field programmable gate array (FPGA) utilized control kernel achieve fully digitalized system. The simulated results are used demonstrate feasibility proposed converter, whereas experimental verify its effectiveness.
