摘　　要：作为培养动手实践能力的重要课程,传统DSP课程教学模式下学生实验课时不足、实践周期较长,导致学习效果下降。为解决这一问题,设计一款以TMS320F28335为核心的DSP “口袋实验室”,并包含仿真器功能模块可有效拓展学生实验场所。“口袋实验室”提供的扩展模块实现低压两电平逆变器,实现单电阻采样重构三相电流实验的硬件支撑。通过“口袋实验室”,学生可将课堂学习的理论知识与实践结合,缩短从理论学习到实践的时间间隔,提升教学效果。In view of the lack of experimental class hours and long practice period of students under the traditional DSP course learning mode,the learning effect is low.As an important course emphasizing the ability of practice,the“Pocket Lab”of DSP can effectively expand students’experimental places.A DSP“Pocket Lab”based on TI company’s TMS320F28335 chip as the core controller is designed to solve the problem,which integrates the simulator,provides expansion modules to realize low-voltage two-level inverter,and realizes the hardware support of three-phase current reconstruction experiment based on single resistor current sampling.By using the“Pocket Lab”,students can combine the theoretical knowledge learned in the classroom with practice,shorten the interval from theoretical learning to practice,and improve their teaching effect.
