High- and medium-frequency, high-voltage device and method of supply for an apparatus with impedance such as a gas-discharge apparatus

摘要

The apparatus with impedance to be supplied is for example an ozoniser 6, subject to a high-frequency, high-voltage current produced by a system consisting of a rectifier 1, a filtering capacitor 2, a breaker set 3, a transformer 4 and a boosting capacitor 5. The system of breakers 3, which produces the pulses converted into high voltage by the transformer 4, is controlled by an oscillator 10 set to the resonant frequency of the secondary circuit of the transformer 4. Preferably, the breakers of the system 3 are thus closed at an instant which corresponds to the minimum of the voltage of the corresponding alternating pulses. Application to high-frequency, high-voltage supply devices for improving their efficiency and increasing the frequency delivered. IMAGE
