Abstract

An integrated switched-capacitor (SC), voltage multiplier (VM) cell and switched-inductor (SL) based high gain DC-DC converter is put forward here. This suggested converter boosts the low voltage obtained from fuel cell or solar photo voltaic (PV) to make it suitable for grid integration. This converter is highly efficient with a gain of 89 when operated with 0.8 duty ratio. The suggested converter switches and diodes are under low voltage stress. In order to validate simulation results, a 100 W, 200 V prototype model is set up in the laboratory for 24 V input. According to the experimental findings, the intended converter is highly effective, owing to its high gain, low switching stress and low duty cycle.

基于开关电感器、开关电容器和倍压器单元的高升压 DC-DC 转换器

摘要

本文提出了一种基于集成开关电容器（SC）、倍压器（VM）单元和开关电感器（SL）的高增益 DC-DC 转换器。该转换器可提高从燃料电池或太阳能光伏（PV）获得的低电压，使其适合电网并网。该转换器效率很高，在占空比为 0.8 时增益为 89。建议的转换器开关和二极管处于低电压应力下。为了验证仿真结果，在实验室建立了 24 V 输入的 100 W、200 V 原型模型。根据实验结果，预期的转换器由于其高增益、低开关应力和低占空比而非常有效。
