SYSTEMS AND METHODS FOR ADAPTIVE GATE DRIVER FOR INVERTER FOR ELECTRIC VEHICLE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240106369 titled 'SYSTEMS AND METHODS FOR ADAPTIVE GATE DRIVER FOR INVERTER FOR ELECTRIC VEHICLE

Simplified Explanation

The system described in the patent application is designed to optimize the turn-on operation of a power switch by using gate driver profiles and threshold values to efficiently control the process. Here is a simplified explanation of the abstract:

  • Point-of-use controllers assert a command-on signal to load a first turn-on gate driver profile.
  • The gate driver is controlled to begin the first phase of the turn-on operation based on the loaded profile.
  • A first power switch signal is received and compared to a first turn-on threshold value.
  • If the signal exceeds the threshold, a second gate turn-on driver profile is loaded.
  • The gate driver is then controlled to end the first phase and begin the second phase of the turn-on operation.

Potential applications of this technology:

  • Power electronics
  • Renewable energy systems
  • Electric vehicles

Problems solved by this technology:

  • Efficient control of power switch turn-on operation
  • Optimization of power management systems

Benefits of this technology:

  • Improved energy efficiency
  • Enhanced performance of power systems
  • Reduction of power losses

Potential commercial applications of this technology:

  • Power electronics manufacturing
  • Renewable energy system integration
  • Electric vehicle production

Possible prior art:

There may be prior art related to gate driver control systems in power electronics, but specific examples are not provided in this abstract.

Unanswered questions:

1. How does this system handle variations in power switch characteristics? 2. Are there any limitations to the number of gate driver profiles that can be loaded and utilized in this system?


Original Abstract Submitted

a system comprises: one or more point-of-use controllers configured to: assert a command-on signal to load a first turn-on gate driver profile; control, based on the loaded first turn-on gate driver profile, a gate driver to begin a first phase of a turn-on operation; receive a first power switch signal based on one or more of a detected voltage or a detected current; perform a comparison of the received first power switch signal to a first turn-on threshold value; load a second gate turn-on driver profile when the comparison indicates the first power switch signal is greater than the first turn-on threshold value; and control, based on the loaded second turn-on gate driver profile, the gate driver to end the first phase of the turn-on operation and begin a second phase of the turn-on operation.
