摘要
文章简单的分析了调频式串联谐振耐压试验系统的电路特性,在频率由低到高的调节过程中低次谐波一旦谐振,输出波形就会严重畸变。提出基于重复控制算法的分段同步单极性SPWM方法进行调频电源的调制,保证了电源大范围变频调压过程中低次谐波少,波形质量高,具有理想单极性SPWM的效果,且开关损耗小。对于谐振回路的频率跟踪,本文提出一种基于TMS320C2812的数字锁相环的实现方法,与传统的频率跟踪方法(集成锁相环CD4046为核心的模拟电路)相比,具有跟踪速度快、跟踪频率准确、抗干扰能力强等有点。
在理论分析的基础上,设计了一套基于TMS320C2812 DSP数字控制器的串联谐振交流耐压试验系统模型样机。样机的仿真结果表明,采用单极性SPWM调制方式实现的自动调频电源输出电压正负半波对称性好,相位稳定,波形正弦度高;验证了数字锁相环具有稳定性好、精度较高的特点。
The article simply analyzed the Pressure circuit characteristics of the simple-FM series resonant system. In the process of adjusting the frequency from low to high, once the low harmonic resonance,and the output wave will be seriously distorted. According to this, the paper presented the method of using sub-synchronous unipolar SPWM to modulation the power FM on the basis of repetitive control algorithm. To ensure that the low harmonic reduction in the process of large-scale frequency regulating, the higher quality of the output wave and the desired unipolar SPWM results,in addition, the less switching loss.
This paper presented an implementation based on the phase-locked loop control technology. Compared with the traditional methods (the integrated phase-locked loop at the core of the analog circuit),this method have those advantages to track the frequency such as fast and accurately tracking the frequency and stronger anti-jamming capability.
On the basis of theory analysis, A prototype of the ACRF test system is developed, which uses DSP TMS320C2812 as the core of control system. Simulation results demonstrate that the output voltage of the system based on subsection synchronization unipolar SPWM modulation and DPLL have high steady-state precision and symmetrical wave form,further more,the phase and frequency of the voltage is both precise and stable.
