The circuit is composed of a rectification, oscillation, boost, and negative ion generating circuit. When the mains enters the power transformer TR through the switch SB and the fuse FU, and then rectifies by the diodes VD1 to VD4, after the capacitor C1 is filtered, the voltage passes through the primary winding N1 of the step-up transformer TU, the potentiometer RP, and the resistor R to the base of the VT. The pole provides a bias voltage, while supplying the collector of the VT through N1 and N2, and the VT starts to conduct. The oscillation of the TU will further strengthen the current of N1, and the current of the VT base will be enhanced, so that the VT is turned from the saturated conduction state to the off state, thereby causing the oscillation circuit to be turned on and off repeatedly.
Winding N2 in the circuit provides a positive feedback voltage for VT, and resistor R and potentiometer RP provide a static bias voltage for VT to form a self-excited oscillator.
