摘要
针对频率可调中频开关电源,采用TMS320LF2812定点32位DSP芯片,通过规则采样法产生三相SPWM波控制三相逆变器,实现频率可调的正弦电压输出。通过PI算法实现三相正弦电压幅值可调的闭环控制,并给出了系统的硬件组成和软件设计。
Considering intermediate frequency Switching Mode Power Supply,we generate the three-phase SPWM waveform by rule sampling method based on TMS320F2812 DSP to control three-phase inverter and produce frequency-convertible sine voltage output.And we also accomplish the closed loop control to convert the amplitudeof three-phase sine voltage by PI control and present the design of hardware and software systerm.
