PURPOSE:To make it possible to change over the voltage quickly, by switching through using a high speed pulse generator which contains a pulse transformer and a switching element. CONSTITUTION:When transistor TR2 is in off condition, the voltage of power source 1 is almost impressed on load 3. Then a pulse voltage is impressed through pulse transformer 7 in the direction which contradicts the voltage impressed on load 3 and, at the same time, a voltage is impressed on TR2 through driving circuit 6 so that TR2 will turn on. By this, the voltage of load 3 is contradicted quickly by the pulse voltage impressed from transformer 7 having a quick built-up. Then TR2 is turned on at the time when the pulse voltage from transformer 7 is almost dimin ished, and both ends of load 3 are shorted. By this, the voltage can be changed over quickly by switching through using a high speed pulse generator containing a pulse transformer and a switching element. |
