LOAD DRIVER - A simplified explanation of the abstract
This abstract first appeared for US patent application 18651298 titled 'LOAD DRIVER
Simplified Explanation: The patent application describes a power converter connected between a power supply line and a ground line, with the power supply line connected to a battery. The power converter converts the battery's direct current power to supply power to a load. A control circuit manages the power converter using a voltage from the battery. A reverse-connection protective relay is linked to the ground line and interrupts current flow from the ground line to the power supply line through the power converter if the battery is connected in reverse.
Key Features and Innovation:
- Power converter converts direct current power from a battery to supply power to a load.
- Control circuit regulates the power converter using voltage from the battery.
- Reverse-connection protective relay interrupts current flow if the battery is connected in reverse.
- Voltage applied to the gate of the relay prevents reverse connection and protects the system.
Potential Applications: This technology could be used in various battery-powered systems where protection against reverse connection is crucial, such as in automotive, renewable energy, and industrial applications.
Problems Solved: The technology addresses the risk of damage to the system due to reverse connection of the battery, ensuring safe and efficient operation.
Benefits:
- Enhanced safety by preventing damage from reverse battery connection.
- Improved efficiency and reliability of battery-powered systems.
- Simplified control and protection mechanisms for power converters.
Commercial Applications: Potential commercial applications include automotive electronics, solar power systems, uninterruptible power supplies (UPS), and industrial machinery.
Prior Art: Readers can explore prior patents related to power converters, reverse connection protection, and battery management systems to understand the existing technology landscape.
Frequently Updated Research: Stay informed about advancements in power converter technology, battery management systems, and safety mechanisms for electrical systems to enhance the understanding of this innovation.
Questions about Power Converter Technology: 1. How does the control circuit in the power converter ensure efficient power conversion? 2. What are the key differences between this reverse-connection protective relay and traditional protection methods?
Original Abstract Submitted
A power converter is connected between a power supply line and a ground line, and the power supply line is connected to a battery. The power converter supplies converted power to a load by converting direct current power of the battery. A control circuit controls the power converter by a voltage applied from the battery. A reverse-connection protective relay is connected to the ground line, and interrupts a current flowing from the ground line to the power supply line via the power converter in a case where the battery is connected in a reverse direction. A voltage required for turning on the reverse-connection protective relay is applied to a gate of the reverse-connection protective relay in a case where the battery is connected in a forward direction, and is not applied to the gate of the reverse-connection protective relay in a case where the battery is connected in the reverse direction.
