The negative oxygen ion generator circuit is designed to produce a flow of negative oxygen ions, which can be beneficial for air purification and improving air quality. The full-wave dual voltage rectifier circuit converts the incoming AC voltage into a pulsating DC voltage, utilizing diodes VD1 and VD2 for rectification. Capacitors C1 and C2 serve to smooth the output voltage, ensuring a more stable DC supply for the subsequent stages of the circuit.

The pulse oscillation circuit is crucial for generating the necessary high-frequency oscillations that drive the negative ion generation process. Transistor V acts as a switch, controlled by the voltage across potentiometer RP, which allows for fine-tuning the oscillation frequency. Resistor R1 provides necessary biasing for the transistor, while capacitor C3 aids in determining the oscillation frequency along with the characteristics of diode VD3, which rectifies the oscillating signal to maintain the pulse shape required for the boost transformer.

The boost transformer (T) plays a vital role in stepping up the voltage to the high levels required for ion generation. The negative high voltage generation circuit utilizes two windings of the transformer to achieve the desired output voltage. The high voltage silicon rectifier stack (VD4) is employed to convert the high-frequency AC output from the transformer into a high DC voltage suitable for ion generation. Resistor R2 and capacitor C4 are included to filter and stabilize the high voltage output, ensuring that the circuit operates efficiently and reliably.
