本公開一般涉及電(dian)力轉(zhuan)換系統，并且更特別(bie)地(di)涉及包(bao)括反激(ji)轉(zhuan)換器(qi)的電(dian)力轉(zhuan)換系統。

背景技術：

1、專(zhuan)(zhuan)利(li)文獻1公開(kai)(kai)了反激(ji)轉換(huan)(huan)器(qi)(qi)系統(電力(li)轉換(huan)(huan)系統)。專(zhuan)(zhuan)利(li)文獻1的(de)反激(ji)轉換(huan)(huan)器(qi)(qi)系統包(bao)括(kuo)：變(bian)壓器(qi)(qi)；一(yi)(yi)次(ci)側(ce)(ce)的(de)第(di)(di)(di)(di)(di)一(yi)(yi)開(kai)(kai)關(guan)(guan)(第(di)(di)(di)(di)(di)一(yi)(yi)半(ban)導(dao)體(ti)切換(huan)(huan)元(yuan)(yuan)件(jian)(jian))；二(er)次(ci)側(ce)(ce)的(de)第(di)(di)(di)(di)(di)二(er)開(kai)(kai)關(guan)(guan)(第(di)(di)(di)(di)(di)二(er)半(ban)導(dao)體(ti)切換(huan)(huan)元(yuan)(yuan)件(jian)(jian))；輸出電容(rong)器(qi)(qi)；第(di)(di)(di)(di)(di)一(yi)(yi)控(kong)制(zhi)電路(lu)；以及(ji)第(di)(di)(di)(di)(di)二(er)控(kong)制(zhi)電路(lu)。變(bian)壓器(qi)(qi)包(bao)括(kuo)一(yi)(yi)次(ci)繞(rao)(rao)組和二(er)次(ci)繞(rao)(rao)組。第(di)(di)(di)(di)(di)一(yi)(yi)開(kai)(kai)關(guan)(guan)包(bao)括(kuo)第(di)(di)(di)(di)(di)一(yi)(yi)開(kai)(kai)關(guan)(guan)電容(rong)(第(di)(di)(di)(di)(di)一(yi)(yi)寄(ji)生(sheng)電容(rong))。第(di)(di)(di)(di)(di)二(er)開(kai)(kai)關(guan)(guan)包(bao)括(kuo)第(di)(di)(di)(di)(di)二(er)開(kai)(kai)關(guan)(guan)電容(rong)(第(di)(di)(di)(di)(di)二(er)寄(ji)生(sheng)電容(rong))。使第(di)(di)(di)(di)(di)一(yi)(yi)開(kai)(kai)關(guan)(guan)響應于(yu)由(you)第(di)(di)(di)(di)(di)一(yi)(yi)控(kong)制(zhi)電路(lu)提供的(de)第(di)(di)(di)(di)(di)一(yi)(yi)切換(huan)(huan)控(kong)制(zhi)信號而操作。使第(di)(di)(di)(di)(di)二(er)開(kai)(kai)關(guan)(guan)響應于(yu)由(you)第(di)(di)(di)(di)(di)二(er)控(kong)制(zhi)電路(lu)提供的(de)第(di)(di)(di)(di)(di)二(er)切換(huan)(huan)控(kong)制(zhi)信號而操作。

2、在專利文(wen)獻(xian)1的(de)反激轉換器(qi)系(xi)統中，第(di)一控制(zhi)(zhi)電路和第(di)二(er)控制(zhi)(zhi)電路通過(guo)進行使(shi)第(di)二(er)開關(guan)(guan)在開始(shi)一次側切(qie)換之前變為導通(on)的(de)高級切(qie)換控制(zhi)(zhi)，來提供第(di)一開關(guan)(guan)電容(rong)(和第(di)二(er)開關(guan)(guan)電容(rong))的(de)受控放電。

3、在(zai)(zai)專利文(wen)獻1的(de)電(dian)(dian)力轉換(huan)(huan)(huan)系統中，為(wei)了(le)使(shi)(shi)第(di)一(yi)開(kai)關的(de)第(di)一(yi)寄生(sheng)電(dian)(dian)容(rong)中的(de)電(dian)(dian)荷放電(dian)(dian)，在(zai)(zai)正在(zai)(zai)進(jin)行高級(ji)切換(huan)(huan)(huan)控制期間，在(zai)(zai)使(shi)(shi)第(di)一(yi)開(kai)關變為(wei)導通(tong)(tong)之前使(shi)(shi)第(di)二開(kai)關變為(wei)導通(tong)(tong)。然而(er)，這涉及硬(ying)切換(huan)(huan)(huan)，該硬(ying)切換(huan)(huan)(huan)導致(zhi)第(di)二開(kai)關的(de)切換(huan)(huan)(huan)損耗增加。

技術總結
本發明的問題是更可靠地進行軟切換。在本發明中，控制器(3)通過在第一時間段中勵磁電流(i<subgt;Lm</subgt;)已開始在負方向上流動以使第一半導體切換元件(Q5)兩端的第一寄生電容(C5)和第二半導體切換元件(Q6)兩端的第二寄生電容(C6)結束被放電之后、使第二半導體切換元件(Q6)變為關斷，來進行向第二時間段中的控制的轉變。第二控制單元(5)控制第一半導體切換元件(Q5)，使得使第一半導體切換元件(Q5)變為導通和關斷的各個定時與第一寄生電容(C5)結束被放電的定時同步。第二控制單元(5)控制第二半導體切換元件(Q6)，使得使第二半導體切換元件(Q6)變為導通和關斷的各個定時與第二寄生電容(C6)結束被放電的定時同步。
