Description
方法および装置が、入力DC信号の増大または減少で用いるために記載される。
出力部26における電圧と入力部24における電圧との間の関係は、以下のように表される。
V_out/V_in = D_1/(1-D_2/2)
V_in = L_m Δi/t_on
である。
ここで、tonは両方の二次スイッチ122a,122bが閉成する継続期間であり、図5に示される用語を用いている。図7は、二次スイッチ122a,122bの位置の経時変化を示し、両方の二次スイッチ122a,122bが閉成する全スイッチングサイクルの周期Tの期間tonを特定している。スイッチング周波数はkHzの領域にあることが想定されているが、本発明はこれに限定されない。
である。
ここで、Tは、図7に示されるように、スイッチングサイクルの周期である。
D=t_on/T
上式を解いて、伝達関数を求める。
V_out/V_in = (2+η) 1/((1-D))
ここで
η=√(L_b/L_a)=√(L_d/L_c)
V_out/V_in = D+((1-D))/((2+η))
