  1. Firstly. operation principle of induction heating is introduced and the actuality of the power supply for induction heating is summarized. then, the scheme of structure of the power supply is established : uncontrolled rectifier and buck chopper constitute dc circuit. in this part, operation principle of a kind of soft switching buck chopper is presented mainly and the conclusion that the power semiconductor devices operate in soft switching is also illustrated by analysing the operation principle of all stages ; series resonant inverter is selected as inverter circuit via comparing the advantage and shortcoming of parallel resonant and series resonant. moreover. the work principle of series resonant inverter is analysed and the calculating method of the best dead time is put forward as well

    文中首先介紹了感應加熱源的工作原理並綜述了國內外的研究現狀。接下來分析並制定了源主的構成方案:在對比幾種功率調節方式的基礎上了不控整流加斬調壓作為直流部分。在這部分里,重點研究了一種軟開關buck變換器,通過分析各階的工作原理說明了開關器件如何工作在軟開關狀態;對于逆變器部分,在比較了串、並聯逆變器優缺點的基礎上了串聯諧振逆變器,並詳細分析了串聯逆變器的工作原理,提出了最佳死區的計算方法。
  2. It includes four criterions of locating fault point ? “ transient zero sequence current amplitude law ”, “ stable base wave zero sequence current phase law ”, “ stable seventh harmonic zero sequence current phase law ” and “ s injection law ”. pointing out how the law locate the fault point to minimal fault section by applying these criterions gradually. the law will not only make up the blemishes existing in current methods for single - phase fault location in small current grounding system, but also locate the fault point to minimal fault isolating unit on fault line

    該方法通過將所包含的四個定位判據- 「暫態零序流幅值法」 、 「穩態基零序流方向法」 、 「穩態7次諧零序流方向法」和「 s信號注入法」 -進行有地遞進使用,不僅有效彌補了目前已有小流接地系統單相接地故障線的缺陷,更將故障定位在故障線最小故障區
