PROBLEM TO BE SOLVED: To provide a power supply circuit for an ion generating apparatus that can generate same and large quantity of minus ions and plus ions. SOLUTION: The power supply circuit has one primary coil 11 which supplies energy to a secondary coil 3 for generating the plus ions and to a secondary coil 4 for generating the minus ions, wherein outputs of two secondary coils 3 and 4 are synchronized mutually. This type of power supply circuit for generating ion cluster by generating the same quantity of plus ions and minus ions is known. However the current power supply circuit cannot generate large quantity of ions. Though a circuit which generates the plus ions only or the minus ions only can generate large quantity of ions, only coupling the circuits cannot generate the same quantity of plus ions and minus ions. The power supply circuit solves the problems. COPYRIGHT: (C)2004,JPO&NCIPI
