Abstract

1485709 D.C.-D.C. inverters for ozonizers and precipitators NISSAN MOTOR CO Ltd and DENKI ONKYO CO Ltd 27 Oct 1975 [29 Nov 1974] 44013/75 Headings H2F and H2H A high voltage generator for a load 6, such as an ozone producer or an electrostatic dust separator, comprises a piezoelectric device 1 having two input electrodes 11, 12 and an output electrode 13, the electrodes 11, 12 being supplied with an alternating voltage produced by an oscillator unit 2, 3 which includes a parallel circuit 32, 312 having a resonant frequency equal to the natural frequency of the piezoelectric device 1 so that the output frequency of the oscillator equals the natural frequency, the output voltage of the piezoelectric device 1 being rectified and doubled by a unit 5, and applied to the load 6, the supply voltage to the oscillator unit 2, 3 from a D.C. source + being maintained constant by a voltage regulator 4 which includes a series transistor 41, the apparatus further being provided with a unit 7 which causes the voltage regulator 4 to become inoperative should the current taken by the load 5 exceed a predetermined level, the unit 7 being provided with a lamp 75 to indicate such an overload current. The unit 7 may comprise a thyristor instead of a pair of transistors or a breakdown threshold element instead of a variable resistor.
