摘要

The present study proposes a simulation model for halogen heater to estimate flicker levels. In the present model of halogen heater, the temperature dependence of filament resistance is taken account for estimation of flicker levels and the temperature is estimated by energy balance of input and output powers. The energy balance is modeled like that an input electric power to a halogen heater filament is dissipated for rise of the filament temperature, the radiation for heating fuser and the loss. The ratio of each power dissipation is determined by the transient response measurement by using an actual halogen heater. The halogen heater model is capable of calculating a filament temperature, a filament resistance and a filament current for any input voltage pattern. Using the current value calculated, a flicker level is obtained by a calculation program developed in accordance with measuring procedure of the flickermeter which is specified by International Standard. Flicker levels for square signals with various period and duty were calculated using the proposed model and compared with those measured by the flickermeter. A good agreement was obtained between the calculation and measurements. The present model enables flicker simulation of fuser temperature control using a halogen heater.
