An electronic circuit consist of few or lots of electronic components for it to function properly. The electronic circuits such as the power supply, vertical, horizontal, high voltage, scanner, audio, color, memory, inverter, converter, feedback and etc are the circuits that forms the purpose of electronic equipment. In other words, different electronic equipment have different task because it has different types of electronic circuits in it. This month article is about to reveal the purpose of some electronic components in those electronic circuits. Let’s begin and analyse those components.
Whenever I draw the diagram of the high voltage circuit of a Monitor, many times my students asked what was the function of the damper diode connected across collector and emitter pin of horizontal output transistor (HOT). For your information the damper diode can be found built into the HOT or in the circuit. Because of the high inductance and interwinding capacitance of the yoke and flyback transformer, the circuit must be damped out during retrace to prevent ringing. In other word, the damper is used to prevent oscillation in electronic circuit.
Note: Ringing means unwanted oscillation of a signal.
