ELECTRIC POWER CONVERSION APPARATUS CAPABLE OF CONTROLLING POWER CONVERSION CIRCUITS TO OPERATE SELECTIVELY AND SEQUENTIALLY - A simplified explanation of the abstract

This abstract first appeared for US patent application 18271189 titled 'ELECTRIC POWER CONVERSION APPARATUS CAPABLE OF CONTROLLING POWER CONVERSION CIRCUITS TO OPERATE SELECTIVELY AND SEQUENTIALLY

Simplified Explanation

- Power conversion apparatus with multiple circuits and a control circuit - Each circuit has a transformer and supplies DC power to a rechargeable battery - Control circuit manages the operation of the power conversion circuits - When battery voltage is at or above a certain threshold, control circuit operates one circuit at a time while others are stopped

    • Potential Applications:**

- Renewable energy systems - Electric vehicles - Uninterruptible power supplies

    • Problems Solved:**

- Efficient power conversion - Battery management - Overload protection

    • Benefits:**

- Extended battery life - Improved energy efficiency - Enhanced system reliability


Original Abstract Submitted

A power conversion apparatus is provided with: a plurality of power conversion circuits each provided with a transformer and supplying DC power to a common rechargeable battery; and a control circuit configured to control the plurality of power conversion circuits. When a load voltage of the rechargeable battery is equal to or higher than a first threshold, the control circuit selectively and sequentially operates the plurality of power conversion circuits such that one of the plurality of power conversion circuits is operated, and others of the plurality of power conversion circuits are stopped.
