Claims
- 1. A high voltage transformer for a television receiver comprising:
- a primary winding;
- a compartmentalized secondary winding separated from said primary winding by a space, said secondary winding having a plurality of partial windings arranged in cells of a compartmentalized coil form and connected to one another by diodes, and
- means for causing substantially equal pulse voltages of like polarity to exist at said primary winding and said partial windings in the vicinity of said space, to substantially eliminate pulse electric fields in said space.
- 2. The transformer of claim 1 wherein said primary winding is wound in layers with several layers lying above each other, and wherein a lead-in wire is provided to a lowest layer for connecting to an operating voltage and a lead-out wire is connected to an upper layer for connecting to a periodic switch.
- 3. the transformer of claim 2 wherein said partial windings are polarized to provide a positive-directed pulse at said lead-out wire.
- 4. The transformer of claim 3 wherein the number and dimensions of said partial windings is selected to be sufficiently large to provide a positive pulse at the base of a cell which has substantially the same amplitude as a positive-directed pulse at the upper layer of said primary winding.
- 5. The transformer of claim 2 wherein the anode of one diode is connected to the lead wire from the base of a cell and the cathode of each said diodes is connected to the lead wire from the upper layer of the partial winding of the next cell.
- 6. The transformer of claim 2 wherein the start of said secondary winnding is the output terminal for supplying a high voltage to said television receiver.
- 7. The transformer of claim 2 wherein said transformer is a split transformer utilizing diodes.
- 8. The transformer of claim 2 wherein said cells are filled by said partial windings whereby the pulses at the base of each of said cells have substantially the same amplitude as the pulses at the neighboring winding of said primary winding.
- 9. The transformer of claim 2 wherein the first and the second of said cells are filled less the the rest of said cells.
