Abstract】 The utility model discloses a transformer feedback oscillator, aims to provide a transformer feedback oscillator with low cost, small power consumption, small size, and strong driving ability. It is realized through the following technical scheme: a transformer feedback oscillator comprises a power supply, a feedback circuit, an amplification circuit, the power supply is connected with any point tap in the middle of the transformer primary winding, one end of the transformer primary winding is connected with one end of the capacitor, and the other end of the transformer primary winding is connected with the amplification end of the amplification circuit after being connected with the other end of the capacitor.

Another scheme is to connect the power supply with any point tap in the middle of the transformer primary winding, the other point tap in the middle of the transformer primary winding is connected with the amplification end of the amplification circuit, and the two ends of the transformer primary winding are connected with the two ends of the capacitor. The amplification circuit is connected with the bias circuit. The capacitor can be a load with capacitive characteristics.

The utility model is mainly applicable to an electroluminescent plate.

Sovereignty Item] 1A transformer feedback oscillator comprises a power supply, a feedback circuit, an amplification circuit, and is characterized in that, the power supply is connected with any point tap in the middle of the transformer primary winding, one end of the transformer primary winding is connected with one end of the capacitor, and the other end of the transformer primary winding is connected with the amplification end of the amplification circuit after being connected with the other end of the capacitor.
