第1のダイオードは、前記電源の正極端子を結合するよう設けられている第1の入力端子と、第1の出力端子へ結合されている前記直列接続されたスイッチの第1端の端子との間に結合され、第2のダイオードは、前記電源の負極端子を結合するよう設けられている第2の入力端子と、第2の出力端子へ結合されている前記直列に接続されたスイッチの第2端の端子との間に結合される、供給回路が提供される。
fres=1/(2π√(Lres・Cres)) (1)
Zres=√(Lres/Cres) (2)
シミュレーション結果に基づいて、回路動作は、次のように説明され得る。すなわち、説明のために、時間インターバルにおいて、共振周期の半分である周期τが定義される:

スイッチM1及びM2のスイッチング周期は、図7から明らかなようにTswitchであり、2×Tres≦Tswitchである。夫々の時間インターバルにおける導通部分は、図9乃至図12に表される。
VC(t=0)=Vout−Vin (4)
である。更に、Cres及びLresでの電圧降下V1が図9から求められる。すなわち、初期条件及び共振キャパシタの電圧VCを用いて、夫々のサイクルが終わった後の夫々の正弦半波の振幅及びキャパシタの電圧VCが計算され得る。サイクルごとに、共振回路全体に印加される電圧V1は、導通部分から求められ得る。第1のサイクルに関しては、V1は:
