摘要： PURPOSE:To realize an efficient resonant type constant-current circuit which does not produce any noises and is easily controlled by connecting an inductance and capacitance which stisfy the resonance conditions to an AC voltage source in series and connecting a load to either one of them. CONSTITUTION:An inductance and capacitance are connected in series to an AC voltage source and the resonance conditions are satisfied in series to the frequency of the AC power, and then, a load is connected to either one of the inductance and capacitance and a constant-current is supplied to the load. That is to say, for example, a reactor 1 and capacitance 2 are connected in series to an AC voltage source Ei and the resonance conditions are satisfied in series to the frequency of the AC power Ei, and then, a load 3 is connected to the capacitance 2 through a current transformer CT. Then a constant-current is supplied to the load 3 by detecting the load current with the current transformer CT and controlling the ignition phase angle of a triode AC switch 7 with a phase shifter 6.
