Abstract: A high voltage drive of aircraft electric brake system was designed. The whole structure of aircraft electric brake system was introduced. The function of aircraft antiskid braking control system, braking driving system and electromechanical actuator braking system was shown. A hardware based on DSP+CPLD and a control strategy of software based on current loop, velocity loop and brake pressure loop were designed. As a result of experiment, the design of the software and hardware of the drive is reasonable and correct. The drive completes the functions of the aircraft brake perfectly. Key words: aircraft brake, brushless DC motor, DSP, CPLD
