Negative power output circuit using output pulse of flyback transformer

摘要

In this study, the voltage pulp generated in the FBT of the display or TV can be used to extract the low-level negative voltage such as audio amplifier, and the output pulse of the aircraft can be used for the sound source output circuit.;For this purpose, on the display screen of the tarmac bag transformer with the output of a certain level of positive energy pulse,Connect the output terminal of the feedback transformer (10), and only the diode (d) rectifying the decimal power supply of the pulse output by the feedback transformer (10),Parallel diode (d) output, smooth the specified decimal power supply (c),Connected to the diode (d) output terminal, a stabilizer (20) is provided to output a smooth decimal power supply to a certain level of voltage.
