Ppfc working principle, circular current and effects of clamping capacitor are studied in this paper in detail. because of the clamping capacitor, ppfc have some good features compared with ppc : reducing the fluctuate of the input current ; restraining the voltage spike of the power mosfet ; avoiding the bias - magnetic of the transformer
由於箝位電容的加入,相對于推挽電路而言,該拓撲具備了一些獨特的優點:減小了輸入電流的脈動:削弱了開關管的關斷電壓尖峰;有效抑制了變壓器的偏磁。Because of the clamping capacitor and the interleaved structure, it has some good features compared with other flyback converters, such as : the topology is simple and can be realized easily ; the voltage spike of the power switch is availably restrained and without leakage - inductance energy loss ; the ripple of the input and output current is reduced, correspondingly, the volume and weight of the output and input filter is also significantly reduced
由於箝位電容的加入,相對于其他類型的反激式變換器電路,該拓撲具有一些獨特的優點:電路結構簡單且易於實現;無需另加輔助開關管,實現了開關管的有源箝位,抑制了開關管的電壓尖峰;提高了輸入、輸出電流的脈動頻率,減小了輸入及輸出濾波器體積。Secondly, considering the need of frequency stabilization, mdrlg ' s light intensity is simulated. the simulations indicate that sharp pulses are produced in the ac light intensity by mechanical dither. as the pulses have a wide frequency spectrum and range over the modulation frequencies of frequency stabilization, mechanical dither may reduce the precision of frequency stabilization
其次,根據穩頻需要對機抖陀螺輸出光強進行了模擬,模擬表明機械抖動會在交流光強中引入尖峰脈沖,且尖峰脈沖頻譜分佈較寬,在小抖動穩頻調制頻率范圍內有功率輸出,因而可能降低穩頻精度。The list betterments aimed at the properties of system : through the testing of dc voltage, pulse width and inverting voltage and frequency can be regulated online to fit for different steady load ; reducing speed ripples by compensating with nonzero voltage working proportional time ; adopting the technology of harmonics suppression. as a result, the high precision and wide speed control is realized and the step out is overcome
針對系統的性能指標,做了如下改進:對直流側電壓的檢測,在線調整逆變器導通脈寬、輸出電壓和頻率,可以適應不同大小的恆負載;並用非零電壓矢量作用時間進行補償的方法,減小電機的低速脈動;加入了諧波抑制技術等。分享友人
