ABSTRACT:
A power supply for an electrostatic air cleaner incorporates a high frequency oscillator and a step-up transformer. The transformer includes a primary winding in series with a transistor, a secondary winding which cooperates with a voltage multiplying means to produce a desired output voltage for energizing the cell, and a feedback winding. The feedback winding is connected in circuit with the emitter-base circuit of the transistor and is responsive to voltage induced therein for effecting repetitive conduction and non-conduction of the transistor. The feedback winding is further connected in circuit with circuit means for adjusting and limiting the biasing of the transistor.
