The invention discloses a high-performance driving device used for a fuel injector electromagnetic valve. The driving device is composed of a storage battery power source, a DC/DC booster circuit, a digital signal processor, a PWM driver, power switch tubes and a current detection module. The storage battery power source is connected with the DC/DC booster circuit, the digital signal processor is connected with the PWM driver and the current detection module, the PWM driver is connected with the DC/DC booster circuit and the power switch tubes, and the power switch tubes are connected with the storage battery power source, the DC/DC booster circuit, the current detection module and the fuel injector electromagnetic valve. A high-end double-voltage time-sharing power supply technology and a low-end current feedback PWM control technology are adopted, in this way, the opening and closing speed of the electromagnetic valve is remarkably increased, energy consumption is greatly reduced, and fuel injection precision is improved.
