Abstract

Purpose The purpose of this paper is to check the Solar Photovoltaic (PV) inverter working condition with modified unipolar switching pulse. The gate pulse for the inverter switches is generated in MATLAB simulation and interfaced with hardware protype. Simulation results can be compared with hardware results. Design/methodology/approach A considerable amount of research has been done on different Pulse Width Modulation (PWM) techniques. Based on the findings, a modified Unipolar Sinusoidal PWM technique was created with one reference signal and two carrier signals+ (one for the positive half cycle and the other for the negative half cycle) and simulated in the MATLAB/Simulink platform. The prototype inverter module receives the simulated switching pulses via dSPACE DS1104 hardware software interfacing board. The hardware implementation has been done, and the hardware results compared with simulation results for various input voltage levels using resistive load. Findings This modified switching pulse has dead band and additional hardware setup is not required. 3-phase multi-level inverter output waveform has been achieved with six switches in this method and with low filter values, pure sine wave output can be obtained in simulation. By this method of switching pulse generation and testing, for every modification in switching pulse hardware gate driver is not required. Resulting time consumption and money investment are lower. Originality/value Modified Unipolar SPWM pulse generation technique is novel method for solar PV inverter. The switching pulse has been designed and tested in both MATLAB/Simulation and hardware prototype inverter. Hardware and software results are identical. This method of pulse generation and hardware implementation has not been done anywhere before.

基于MATLAB/Simulink模型与dSPACE DS1104接口的太阳能光伏单极SPWM逆变器

目的用改进的单极性开关脉冲检测太阳能光伏逆变器的工作状态。在MATLAB仿真中生成了逆变器开关的栅极脉冲，并与硬件原型进行了接口。仿真结果可以与硬件结果进行比较。设计/方法/方法对不同的脉宽调制（PWM）技术进行了大量的研究。基于这些发现，利用一个参考信号和两个载波信号+（一个用于正半周，另一个用于负半周）创建了一种改进的单极正弦PWM技术，并在MATLAB/Simulink平台上进行了仿真。原型逆变器模块通过dSPACE DS1104软硬件接口板接收模拟的开关脉冲。完成了硬件实现，并将硬件结果与使用电阻负载的各种输入电压电平的仿真结果进行了比较。Findings此修改后的开关脉冲具有死区，不需要额外的硬件设置。该方法利用六个开关实现了三相多电平逆变器的输出波形，并且在低滤波值的情况下，可以在仿真中获得纯正弦波输出。通过这种开关脉冲产生和测试的方法，对于开关脉冲硬件的每次修改都不需要栅极驱动器。由此产生的时间消耗和金钱投资较低。独创性/价值改进的单极SPWM脉冲产生技术是太阳能光伏逆变器的一种新方法。开关脉冲已经在MATLAB/Simulation和硬件原型逆变器中进行了设计和测试。硬件和软件结果完全相同。这种脉冲产生和硬件实现的方法以前从未进行过。
