UN/UC2=D/(1−D)
および
iL2/iL1=(D−1)/D
となり、ここでは損失はないものと仮定される。これらの式は、インバータ3がD<0、5のときバッキングモードで操作され、D>0、5の場合ブースティングモードで操作されるということを示している。
UN/UC2=D/(1−D)
および
iL2/iL1=(D−1)/D
が当てはまることを言及しておく。ただし、ここでも損失はないと仮定する。正の半波と同様に、ブーストおよびバッキングモードの両方の操作が可能である。
D(t)=M/(M+1)
および
M=UN/UC2=D/(1−D)
は、インバータ3の出力部8、9の出力電圧と入力部6、7の入力電圧との間の比を示している。切り替え器S2、S6は、切り替え器S1、S5に対して相補的に切り替えられる。
