Abstract
A circuit for suppressing interference pulses occurring in transformers with high leakage inductance. The circuit includes current controlled switches connected to the transformers having secondary windings. The switches are controlled by a trigger circuit and a control device. The interference pulses are suppressed by a pulse suppression circuit connected between the secondary windings of the transformers and the trigger circuit. Furthermore the transformers' secondary windings are interconnected in phase to the pulse suppression circuit. The correct interconnection is controlled and/or indicated.
Claims7
A circuit for the suppression of interference pulses in at least first and second transformers having high leakage inductances and having first and second current controlled switches connected to said transformers, said first transformer havin a first secondary winding and said second transformer having a second secondary winding, said current controlled switches controlled by a trigger circuit and a control device connected thereto, said suppression circuit comprising:
- (a) pulse suppression means connected between said secondary windings and said trigger circuit, and
- (b) means for interconnecting said two transformers secondary windings in phase to said pulse suppression means.
