  • Control circuit for an A.C. discharge lamp
    Patent number: 4180764
    Abstract: A control circuit comprising a series transductor coupled between an A.C. source and an A.C. discharge lamp. The control windings of the series transductor are connected to the A.C. source through a filter, a full-wave rectifier, and a substantially capacitive impedance. As a result the total reactive effect is reduced.
