摘要
提出了一种用于逆变器的高分辨率单极脉宽调制器(UPWM)实现技术。单极开关逆变器具有效率高、谐波失真小的优点。该技术在2kW逆变器上进行了典型LC滤波器的测试,总谐波失真低于2%。给出了仿真和实验结果。该技术在MATLAB/Simulink中使用Xilinx System Generator开发,并在片上系统(System on Chip) XC70Z020CLG484-1 Zynq器件上实现。
Implementation of high resolution unipolar PWM inverter using Xilinx System Generator
This paper presents an implementation technique of a high resolution Unipolar Pulse Width Modulator (UPWM) for power inverter applications. Unipolar switched inverter has the advantage of a higher efficiency and lower harmonic distortion. The technique was tested in a 2kW inverter with a typical LC filter and it was achieved a Total Harmonic Distortion below 2%. Simulations and experimental results were performed. The technique was developed with the Xilinx System Generator in MATLAB/Simulink and it was implemented on a System on Chip XC70Z020CLG484-1 Zynq device.
