PROBLEM TO BE SOLVED: To provide a horizontal deflection output circuit capable of reducing power loss for the entire circuit, even if a horizontal deflection frequency is high. SOLUTION: A first switching circuit is constituted of a parallel circuit of a bipolar transistor 11 and a damper diode 13, and a second switching circuit is constituted of a parallel circuit of an FET 19 and a damper diode 21. Resonance capacitors 14, 22, 15 are connected with the first and the second switching circuits. The circuit is constituted so that a time when the drain current of the FET 19 is turned off is placed within the falling time of collector current of the bipolar transistor 11 or within a period to precede a starting point of the falling time by only a time interval which is almost equivalent to the length of the falling time. |
