The hardware platform consists of a BLDC MOTOR(rated speed is 60000rpm), a Buck circuit and an inverter. Under the control of DSP28035, this system can achieve the goal of adjusting the MOTOR’s speed with voltage and the function of sensorless control based on the coordinate transformation. By making full use of resources of the core, such as CLA, analog comparator, HPWM and AD converters, the whole system can meet the requirements.1 引言高速永磁無刷直流電機驅動系統由于基波頻率較高（一般在1kHZ以上），利用逆變橋斬波進行調速的控制方式通常會受到開關管開關頻率的限制，因此該系統多采用三相全橋前級加Buck電路進承擔調壓調速的功能，而三相全橋主要承擔邏輯換相的功能。然而，傳統Buck電路所需電感的體積較大，增加了系統的體積，降低了系統的功率密度。
