CONTROL DEVICE FOR A DRIVE SYSTEM, DRIVE SYSTEM, METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18580599 titled 'CONTROL DEVICE FOR A DRIVE SYSTEM, DRIVE SYSTEM, METHOD
The invention is a control device for a drive system with an electric motor connected to an electrical power storage device through a power electronics unit. The control device is designed to set a safe operational state in the power electronics unit when a fault is detected in the drive system and/or the control device.
- The computing unit determines a control instruction based on the current actual rotational speed of the motor and stores it in the gate driver circuits.
- The gate driver circuits set the safe operational state according to the stored control instruction when a fault is detected.
Potential Applications: - Electric vehicles - Industrial machinery - Renewable energy systems
Problems Solved: - Ensuring safe operation of drive systems - Preventing damage in case of faults
Benefits: - Increased safety - Enhanced system reliability - Protection against damage
Commercial Applications: - Automotive industry for electric vehicles - Manufacturing sector for machinery - Energy sector for renewable energy systems
Questions about the technology: 1. How does the computing unit determine the control instruction based on the motor's rotational speed? 2. What are the specific safety features implemented in the control device to prevent faults?
Frequently Updated Research: - Ongoing advancements in power electronics technology - Research on fault detection and prevention in drive systems
Original Abstract Submitted
The invention relates to a control device () for a drive system () which has an electric motor () electrically connected by a power electronics unit () to an electrical power storage device (), the control device () having a computing unit () and a plurality of gate driver circuits () and being designed to set a safe operational state in the power electronics unit () when a fault in the drive system () and/or the control device () is detected. The computing unit () is designed to determine a control instruction in accordance with a current actual rotational speed (n) of the motor () and to store the control instruction in the gate driver circuits (), and the gate driver circuits () set the safe operational state according to the stored control instruction when a fault is detected.
