DRIVE SYSTEM AND VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18587015 titled 'DRIVE SYSTEM AND VEHICLE
The abstract describes a drive system that includes two inverters and a control part for PWM control to optimize power output to an electric motor propelling a vehicle.
- First inverter outputs alternating current by switching direct current with a first switching element.
- Second inverter supplies alternating current to the electric motor by switching direct current with a second switching element.
- Control part performs PWM control to adjust the ON-time of the switching elements based on the direct current input.
Potential Applications: - Electric vehicles - Hybrid vehicles - Industrial machinery
Problems Solved: - Efficient power distribution to electric motors - Optimal performance of the drive system
Benefits: - Improved energy efficiency - Enhanced vehicle performance - Reduced environmental impact
Commercial Applications: Title: "Efficient Drive System for Electric Vehicles" This technology can be used in electric vehicles, hybrid vehicles, and industrial machinery to improve energy efficiency and overall performance, leading to a competitive advantage in the market.
Questions about the technology: 1. How does the PWM control optimize power output in the drive system?
- The PWM control adjusts the ON-time of the switching elements to match the direct current input, ensuring efficient power distribution to the electric motor.
2. What are the key advantages of using two inverters in the drive system?
- Having two inverters allows for better control and optimization of power output, leading to improved performance and energy efficiency.
Original Abstract Submitted
A drive system includes: a first inverter that outputs first alternating current by switching first direct current with a switching element (first switching element), to an electric motor generating power for propelling a vehicle; a second inverter that supplies, to the electric motor, second alternating current having the same frequency as the first alternating current by switching direct current with a switching element (second switching element); and a control part that performs PWM control on the first inverter and the second inverter such that an ON-time of the first switching element in one cycle of the first alternating current becomes longer than an ON-time of the second switching element when the direct current is smaller than the direct current.
