Abstract

A power conversion system and a coupled double-stage inductance. The power conversion system includes a first voltage conversion unit, a second voltage conversion unit and a shared switch. The first voltage conversion unit includes a first inductor and a first capacitor. The first inductor is electrically connected to the first capacitor. The second voltage conversion unit includes a second inductor and a second capacitor. The second inductor is electrically connected to the second capacitor. The common switch is electrically connected to the first voltage conversion unit and the second voltage conversion unit. The first voltage conversion unit and the second voltage conversion unit share the common switch. When the common switch is connected, the first voltage conversion unit and the second voltage conversion unit perform a two-stage power conversion procedure at the same time sequence.

Description

technical field [0001] The invention relates to an electric energy conversion system and a coupled double-stage inductance. Background technique [0002] With the development of electronic technology, various electronic devices are constantly being introduced. The voltage specifications used by various electronic devices are not the same, so there is a need for a power conversion system. In the existing power conversion system, we can find that a single-stage power conversion system with a high step-down ratio will reduce the conduction rate of the switch. Such a power conversion system has poor precision and poor stability, is easily interfered by noise (noise) to reduce power conversion efficiency, and requires a high-cost control unit. Contents of the invention [0003] The purpose of the present invention is to provide a power conversion system and a coupled double-stage inductor, which utilizes circuit optimization and integration, so that a single common switch can...
