We use the internal AD converter to real-time sampling the referenced grid voltage signal, outputting voltage of photovoltaic, feedback outputting voltage and current signal. The PWM module generates SVpwm according to the calculation of the real-time sampling data, to control the full MOSFET inverter bridge output sine wave. We realized that the output voltage of the simulator can track the frequency and phase of the referenced grid voltage with PI regulation, and the maximum photovoltaic power tracking with constant voltage regulation, thereby achieved the purpose of grid-connected simulation. Additionally, this device has the over-voltage and over-current protection, audible and visual alarm, islanding detecting and protection, and it can recover automatically. The testing shows that our design is feasible.Keywords: Photovoltaic Grid-connected,MPPT,DSP 目錄引言 11. 方案論證 11.1. 總體介紹 11.2. 光伏電池模擬裝置 11.3. DC-AC逆變橋 11.4.

基于TMS320F28035芯片為控制核心的空間矢量異步電機(jī)變頻器 我們?cè)O(shè)計(jì)的異步電機(jī)變頻調(diào)速器以TMS320F28035芯片為控制核心,通過(guò)輸出三相PWM波控制智能功率模塊IPM驅(qū)動(dòng)三相異步電機(jī)。我們使用空間矢量SVpwm算法,并對(duì)其進(jìn)行了優(yōu)化。采用檢測(cè)反電勢(shì)的方法省去了昂貴的光電編碼器,大大節(jié)省了成本。同時(shí)開(kāi)創(chuàng)性的研發(fā)了自動(dòng)根據(jù)運(yùn)行環(huán)境調(diào)節(jié)的自適應(yīng)變頻算法,使我們的變頻調(diào)速器可以在電網(wǎng)條件惡劣的鄉(xiāng)村山區(qū)工作,由此該變頻器已被一家民用水泵生產(chǎn)企業(yè)預(yù)訂。關(guān)鍵字 變頻器 TMS320f28035 IPM SVpwm In our design, the asynchronous machine inverter based on the chip of TMS320F28035 drives the three-Phase asynchronous machine by sending three-phase PWM waves to the IPM, which is short for the Intelligent-Power-Module. The SVpwm (space vector pulse width modulation) strategy is applied to our control algorithm and we optimize it mainly in two aspects. Firstly the inverter detects the speed by measuring the Back EMF instead of installing an expensive photoelectric encoder for costs reduction.
