Abstract

The purpose of this research is to come up with an original design for a high-step-up dc-dc converter that might be used in decentralised power plants. This concept is built on a foundation of a pair of capacitors and a single inductor that is coupled together. The energy that is stored in the connected inductor is used to charge the two capacitors in parallel during the time when the switch is off and to discharge them in series during the time when the switch is on. This results in a high step-up voltage gain. In addition, the energy lost by the linked inductor's leaky inductance may be recycled via the use of a passive clamp circuit. As a result, the strain that the primary switch experiences from the voltage is minimised. Utilizing a switch that has an RDS that has a low resistance may help reduce the amount of conduction loss (ON). Since the problem with the diodes' reverse-recovery has been fixed, the efficiency could be able to be improved even more. There is a focus on providing in-depth descriptions of the operating principle as well as steady-state investigations.

带耦合电感的交错DC-DC升压变换器

本研究的目的是提出一种可能用于分散式发电厂的高升压dc-dc转换器的原始设计。这个概念是建立在一对电容器和一个电感耦合在一起的基础上的。存储在连接的电感中的能量用于在开关断开时对两个电容器并联充电，在开关打开时对它们进行串联放电。这导致了高升压增益。此外，连接电感漏感所损失的能量可以通过使用无源钳位电路进行回收。因此，初级开关从电压经历的应变是最小的。使用具有低电阻RDS的开关可能有助于减少导通损耗(ON)的量。由于二极管反向恢复的问题已经解决，效率可能会进一步提高。重点是提供对工作原理的深入描述以及稳态研究。
