AN INONIZER CIRCUIT FOR DISCHARGING LARGE CAPACITY

摘要

A high-capacity ionizer circuit is disclosed, which is capable of preventing deterioration of an ionization rate caused by ion rebonding. The high-capacity ionizer circuit according to the present invention comprises: a dual high-voltage transformer having a coil wound thereon for ensuring set voltage output and having a dual structure; a positive output circuit connected to an output end of the dual high-voltage transformer to supply a high voltage to a discharge pin in order to discharge anions and cations, respectively; an upper oscillation circuit and a lower oscillation circuit connected to each input end of the dual high-voltage transformer to induce the voltage output; a power supply unit for supplying bias voltage to each of the upper and lower oscillation circuits; a pulse control unit for supplying a pulse signal for controlling the switching of each of the upper and lower oscillation circuits; and a controller for supplying, to the pulse control unit, a duty signal corresponding to an average of each duty depending on a current temperature and humidity. Thus, the high-capacity ionizer of the present invention can be applied to public transportation such as buses or subways and can also discharge the anions and cations of an ionizer alternately to prevent deterioration of an ionization rate caused by ion rebonding, thereby maximizing the efficiency of the ionizer.
