The conventional switching power supply usually use a diode rectifier followed by a bulk capacitor to convert ac voltage to dc voltage, resulting in the pulsating waveform of the input ac line current, low power factor ( generally 0. 65 ) and high harmonic line current
傳統的開關電源設備通常採用二極體橋來進行整流和一個較大的電解電容來進行濾波以實現輸入電壓的交直流轉換,導致輸入電流為一個很窄的脈沖波並含有較多的諧波分量,功率因數變低(通常只有0 . 65 ) 。To shorten charging time and improve charging efficiency, the circuit can change the charging electric current automatically according to real time voltage of the battery, and dispel the polarization phenomenon by narrowing pulse discharge in the whole course
該電路可根據蓄電池端電壓自動改變充電電流大小,並通過全程窄脈沖放電消除了充電過程中的極化現象,縮短了充電時間,提高了充電效率。The second reason is the nonlinear rectifier with a bulky capacitor in the input stage of the smps, which leads to a narrow pulse and rich harmonics
原因之二是開關電源的輸入端採用二極體整流,後接較大的濾波電容,導致輸入電流為一很窄的脈沖波,含有豐富的諧波分量。On the basis of improvement of a simple but effective three - level svpwm algorithm, a simple neutral point balancing and narrow pulse elimination algorithm without current sensor is proposed. and dead time is compensated in the algorithm also
本文在對一種簡潔高效的三電子svpwm演算法改進的基礎上,提出一種無電流傳感器的中點電位控制和窄脈沖消除方法,同時進行了死區的補償。分享友人
