本論文提出之D類串聯負載共振式換流器具有電路結構簡單、體積小、重量輕、低切換損失、成本價格低的優點。共振槽是利用電感與電容所組成的，以共振產生所需的電壓和電流，經零電壓或零電流切換來達到柔性切換技術，減少開關在切換時所造成的切換損失，得到所需的輸出電壓和輸出電流。本論文也針對電路操作特性原理與電路模式加以分析，且將此電路應用於負載在200W。最後，以模擬與實作電路結果驗證，其效率在80%以上。

In this thesis, the Class-D series loaded resonant inverters is proposed which has these advantages such as simpler circuit structures, smaller volume, lighter weight, higher efficiency, low switching loss, as well as lower cost. An L-C resonant tank is used to generate the voltage and current needed. With the zero voltage and zero current switching, the soft-switching technique is to reduce the losses of switching. The operating principles and equivalent circuit are analyzed and discussed in detail. Finally, the simulation and experimental results are conducted for a load is designed in 200W, the efficiency can reach 80% above.
