Abstract |
This paper suggested the sulfur lamp power supply using Fuzzy Gain Scheduling(FGS), which was designed and confirmed the performance through manufacturing. it was based on Series Resonant Half Bridge Inverter(SRHBI), so that was applied Pulse Frequency Modulation(PFM), Zero Voltage Switching(ZVS),soft switching and soft start for input power variation and output power compensation. In order to get the lengthened life time of magnetron and stabilized output of power, power factor and efficiency were improved by fuzzy gain algorism. It also made it possible to get not the existing fixed output power but continuous variable output power(900∼1250[W]). The manufactured power supply showed good results in input power 220[V]±15[%] with stabilized output of power, luminous efficiency 97[lm/W] and power factor 96[%]. |
