IPC: H05B41/18
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To miniaturize pulse transformers without causing electric breakdown and ensure good start without mulfunction due to radiation noise. SOLUTION: Pulse transformers 2a, 2b which have the ends passed through through-holes in holders 10a, 10b are parallelly fixed up and down in a simple structure and arranged with the winding ends of the secondary windings mutually opposed at the right and left sides so that the high voltage parts of the pulse transformers can be separated each other.
