| Abstract: | This paper introduced a new boost converter with a high input-output voltage conversion ratio.The converter included two boost inductors and two switches.The output voltage regulation of the proposed converter is achieved in a wide load and input voltage range with constant-frequency controlled by employing an auxiliary transformer that couples the current paths of the two boost inductors.The performance of the proposed boost converter is verified on a 1kW prototype circuit. |
