摘要
针对EAST快控电源缩短电流响应时间的要求,升级的快控电源控制器采用TMS320F28335替代原快控电源支路控制器中的TMS320F2812,实现响应和输出脉冲宽度调节(PWM)控制上的载波相移,提高系统等效开关频率,减小输出电压响应延时。经过实验验证,升级的快控电源控制器实现预定目标,有助于提升EAST装置抑制等离子体垂直位移不稳定性的能力。
To meet the demand for shortening the response time of EAST fast control power supply, TMS320 F28335 is used to replace TMS320 F2812 as control chip for fast control power supply branch controller. The carrier phase shift of output PWM(pulse width modulation) waveforms is realized to improve the system equivalent switch frequency, which can reduce the output voltage response delay time of power supply. The experimental results show that upgraded controller has achieved the desired target, which is helpful to enhance the ability of EAST devices to suppress the vertical displacement instability of the plasma.
