DSP Based Novel High Voltage High Frequency Electric Source with Self-tuning Ability

Design method for a class of novel high voltage high frequency electric source was investigated. This electric source could serve as discharging device for both corona generator and ozone generator. Through self-turning of power angle, the electric source could adjust itself within a certain frequency according to variations of the loads. In this way, the electric source could stay within the state of resonance oscillation so as to maximize discharging efficiency. Using TMS18LF2407A (DSP component produced by TI corporation) as the core device, the electric source guaranteed high working frequency and strong control functions.
