Feasibility study of existing 50/60Hz electrical appliances for HFAC power distribution systems
This paper investigates into the key parameters (e.g. voltage, frequency, waveform, etc. of HFAC Power Distribution Systems (PDS) ranging from smaller 0.5 kW laptop/desktop computer upto 1.0 MW domestic/commercial/industrial power distribution applications. Due to the high reactance and associated issues observed with increased frequency, different HFAC PDSs have been designed to operate with different frequencies. Advantages of using HFAC over utility AC (50/60Hz) or DC in PDSs predominantly connected with electronic converters has been presented in many publications. Although most electrical appliances are intended to operate mainly with utility AC, it would facilitate widespread uptake of HFAC in PDSs if they could operate also at HFAC. The possibility of cross matching and using a wide variety of electrical appliances on HFAC PDSs has been investigated and the findings are presented in this paper. Use of AC AC power converters as interfacing devices for the appliances that do not perform well with HFAC has also been proposed.
