Abstract (en)
[origin: EP3467975A1] Described herein is an ionisation system (100) which is used to generate a balanced ionisation field in an ionisation chamber (160) from a DC input voltage (105), the ionisation field being used to ionise a gas flow introduced into the ionisation chamber. The ionisation system (100) further comprises a programmable DC-to-DC converter (110) controlled by pulse-width modulation signal (192) from a controller (190) to generate an adjustable DC voltage for a high voltage generator (120). The high voltage generator comprises circuitry to convert the adjustable DC voltage into a high frequency, high voltage AC output which is applied to ionising electrodes (150a, 150b) in the ionisation chamber to generate the ionisation field. Ionised gas stream (180) output from the ionisation chamber is balanced with respect to the number of negative and positive ions generated by the ionisation field.
