POWER SOURCE SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18430786 titled 'POWER SOURCE SYSTEM

The power source system described in the abstract consists of three battery strings, each containing multiple batteries capable of producing direct current power. These battery strings are Y-connected to generate three-phase alternating current power for output to three-phase output terminals, along with a connection to a neutral line. The neutral line features a neutral line capacitor, a neutral line switch, and an electric resistance element to manage the flow of direct current.

• The power source system includes three battery strings with multiple batteries capable of outputting direct current power.
• The batteries are Y-connected to produce three-phase alternating current power for output to three-phase terminals.
• A neutral line is incorporated, with components such as a neutral line capacitor, a neutral line switch, and an electric resistance element to regulate direct current flow.

Potential Applications: - This technology can be used in industrial settings where three-phase power is required. - It can also be utilized in renewable energy systems to convert direct current power from batteries into usable alternating current power.

Problems Solved: - Efficiently converting direct current power from batteries into three-phase alternating current power. - Managing the flow of direct current on the neutral line to ensure stable power output.

Benefits: - Provides a reliable and stable power source for various applications. - Optimizes the use of battery power by converting it into usable three-phase alternating current power.

Commercial Applications: Title: Three-Phase Battery Power Source System for Industrial and Renewable Energy Applications This technology can be commercialized for use in industrial machinery, renewable energy systems, and backup power solutions for critical infrastructure.

Questions about the Three-Phase Battery Power Source System: 1. How does the Y-connection of battery strings contribute to the efficiency of power conversion? 2. What are the key advantages of using a neutral line capacitor in this power source system?

Original Abstract Submitted

A power source system includes a first battery string, a second battery string, and a third battery string. Each of the battery strings includes a plurality of batteries capable of outputting direct-current power. The battery strings are Y-connected so as to output three-phase alternating-current power to three-phase output terminals (alternating-current output terminals) as well as connected to a neutral line. On the neutral line, a neutral line capacitor for blocking a direct current, a neutral line switch disposed in series to the neutral line capacitor, and an electric resistance element disposed in parallel to the neutral line switch are provided.
