パルス幅圧縮回路Ａ３が縦続的に接続されている。On the primary side of this booster T, a pulse width compression circuit A is formed by connecting a capacitor C and a saturable inductor Sll in parallel and series.
1 is connected to the pulse width compression circuit A2, which similarly consists of a capacitor C2 and a saturable inductor ST2.
