LINE DEFLECTION CIRCUIT |
摘要 |
An electronic circuit for switching an inductive load (10) by means of a bipolar transistor (1) whereby a switching signal is supplied to the base (5) of a switching transistor (1) via an LRC circuit (6, 7, 9). During switching off the LRC circuit (6, 7, 9) causes a peak voltage at the base (5) of the switching transistor (1). The value of the peak voltage is a maximum when the power dissipation of the switching transistor (1) is a minimum. A regulator circuit (12-17) regulates a current source (18) in a primary winding of a switched transformer (22) in such a way that the peak voltage (Vp) is maximized. |
