  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電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電源主電路的構成方案:在對比幾種功率調節方的基礎上選擇了不控整加斬波調壓作為直部分。在這部分里,重點研究了一種軟開關buck變,通過分析各階段的工作原理說明了開關件如何工作在軟開關狀態;對于部分,在比較了串、並聯優缺點的基礎上選擇了串聯諧振,並詳細分析了串聯的工作原理,提出了最佳死區的計算方法。
  2. The research results show that the counter - flow condensers have a better performance than that of other arrangements in single - circuit condensers, and that branch flow should be adopted in multi - rows condensers to decrease the pressure drop and increase the heat transfer capacity, and that the influence of gravity force can not be ignored, and that there must be an optimum refrigerant mass flow which can make the condenser perform best when the air velocity is constant while there must be an optimum air flow which can make the condenser perform best when the refrigerant mass flow is constant
