Abstract

PURPOSE:To stabilize the output of a multioutput DC constant current converter in high accuracy and to prevent the influence between the outputs of the converter by connecting an LC series resonance circuit between a plurality of AC output terminals and a rectifying circuit. CONSTITUTION:LC series resonance circuits 37, 38 are connected between a plurality of AC outputs 19, 20 and rectifying circuits 27-30, 31-34. When a transistor 14 is conducted by a drive pulse 13, the transistor 14 is conducted during a period represented by an equation I by a series resonance circuit 37. When a load voltage VA is smaller than the voltage nE of the secondary coil 29 of a transistor 11, a current of reverse direction to that in the previous period is returned through a diode 16 to a DC power source 12 during the period of next pi.(LC)<1/2>, where n represents the ratio of the number of turns of the transformer 11. The switching frequency f of the transistor and the resonance frequency f0 become as equations II. If the input voltage is represented by E, the output current IA becomes IA=8nfCE, wherein 2f<=f0, VA<=nE, and the output current becomes constant irrespective of the load.
