ABSTRACT:
A deflection circuit for a television includes two semiconductor switching elements connected in series. Separate control circuits are provided for each semiconductor switching element to control the operation of the respective switching element. Each control circuit receives a control signal and is connected to a voltage source. For the control circuit associated with the switching element which receives the highest voltage, connection to the voltage source and the control signal is through diodes which provide common mode isolation. This control circuit includes a capacitor which provides energy for the control circuit when the diode connecting it to the voltage source is reverse biased.
