POWER SUPPLY SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18421135 titled 'POWER SUPPLY SYSTEM

Simplified Explanation: The patent application describes a battery string configuration that allows multiple battery circuit modules to be connected in series. The drive circuit transmits gate signals for switching the circuit on and off, with a predetermined delay time to prevent frequency increase.

• The battery string configuration enables connection of multiple battery circuit modules in series.
• The drive circuit transmits gate signals for switching the circuit on and off.
• A predetermined delay time is used to prevent frequency increase.
• The delay time is adjusted when passing through a specific battery circuit module to maintain signal period.
• The longer delay time helps suppress an increase in frequency and loss.

Potential Applications: This technology can be applied in various battery systems, energy storage solutions, electric vehicles, and renewable energy systems.

Problems Solved: - Preventing frequency increase in battery circuit modules connected in series. - Maintaining signal period to avoid loss in the system.

Benefits: - Improved efficiency in battery systems. - Enhanced control over battery circuit modules. - Reduced loss and frequency increase.

Commercial Applications: Title: Advanced Battery String Configuration for Enhanced Efficiency This technology can be utilized in battery manufacturing, electric vehicle production, renewable energy projects, and energy storage solutions. It offers a competitive advantage by improving system performance and reducing energy loss.

Prior Art: Research on battery circuit configurations and delay time adjustments in series-connected modules can provide insights into similar technologies.

Frequently Updated Research: Ongoing research on battery management systems and energy storage technologies may provide further advancements in this field.

Questions about Battery String Configuration: 1. How does the delay time adjustment impact the efficiency of the battery circuit modules? 2. What are the potential challenges in implementing this technology in large-scale energy storage systems?

Original Abstract Submitted

The battery string is configured so that a plurality of battery circuit modules can be connected in series. The drive circuit SU from the drive circuit SU of the battery circuit module transmits a gate signal for ON/OFF of the switch to the downstream drive circuit SU while delaying the gate signal by a predetermined delay time Td. When a particular battery circuit module (drive circuit SU in FIG. ) is passed through, the delay time is switched from the delay time Td to the delay time Tds. The delay time Tds is longer than the delay time Td. As a result, the period of the gate signal, which is the “delay time×the number of battery circuit modules to be operated”, can be suppressed from becoming short (the increase in frequency can be suppressed), and an increase in loss can be suppressed.
