The traditional interleaved two transistor forward converter exists high voltage stress of freewheeling diode when applied in high output voltage condition. 傳統(tǒng)交錯并聯(lián)雙管正激組合變換器應用于高電壓輸出場合時存在變換器次級電壓偏高、高頻整流二極管電壓應力大的問題。
Its key idea is that integration of GTO with improved structure, antiparallel freewheeling diode and gate drive circuit, then connects its gate drive by low inductance. 它的關(guān)鍵思想是將改進結(jié)構(gòu)的GTO與反并聯(lián)二極管和門極驅(qū)動電路集成在一起，再與其門極驅(qū)動器在外圍以低電感方式連接。
The torque ripple caused by diode freewheeling of the inactive phase during non-commutation state of PM brushless DC motor(BLDCM)when using the PWM_ON type of pulse width modulation was analyzed. 分析了傳統(tǒng)的PWM_ON調(diào)制方式對無刷直流電動機在非換相期間由于截止相的反并聯(lián)二極管續(xù)流而導致轉(zhuǎn)矩脈動的原因。
