<p>PROBLEM TO BE SOLVED: To miniaturize and provide high output, by providing an extra coil groove between plural secondary coil grooves formed at a bobbin, mounting a diode at both ends of the coil part, and drawing the intermediate part of the secondary coil, for narrower coil space. SOLUTION: A bobbin of a high voltage transformer has a structure in which an extra coil groove 5 is provided at the center of a coil part, and high voltage pulse rectification diodes 1a and 1b are mounted on both sides of the coil part. Relating to the circuit of the high voltage transformer, a wire, after winding a secondary coil 7a, passes the extra coil group 5, and connects to the diode 1a at the intermediate part. It passes the extra coil groove 5 again from the diode 1a, and after winding a secondary coil 7b, connects to the diode 1b at the last stage. With this circuit configuration, a high voltage pulse 8b on secondary side can be divided to lower a voltage per one pulse, for raised breakdown voltage against a core, so that a high voltage transformer can be smaller in size, in addition, the number of winding times of the secondary coils 7a and 7b can be increased for high output.</p> |
