Patent ID: 8011327

Claim:
A variable voltage electronic pet training apparatus comprising: a controller producing a correction pulse switch activation signal, said controller producing a power converter drive signal corresponding to a selected stimulus intensity; a power converter in communication with said controller, said power converter producing a first voltage corresponding to said power converter drive signal; a transformer having a primary and a secondary, said primary in communication with said power converter, said secondary having an output representing a correction stimulus at said selected stimulus intensity; a correction pulse switch in communication with said controller, said correction pulse switch in communication with said primary, said correction pulse switch selectively connecting said primary to one of said first voltage and a second voltage and producing a primary voltage across said primary equal to the difference between said first voltage and said second voltage wherein said correction stimulus is controlled by adjusting said primary voltage as a result of varying said first voltage using said power converter; and a pair of electrodes connected to said secondary, said pair of electrodes transferring said correction stimulus to an animal.
