Power supply device for ozone generator, and ozone generating device

A power supply device for an ozone generator, which applies electric power to an ozone generator which generates ozone by silent discharge from gas containing oxygen, comprising

• a transformer which transforms a voltage which is applied from a commercial AC power supply,
• an inverter which converts an AC voltage which is transformed by the transformer to be an AC voltage having higher frequency than a frequency of the commercial AC power supply
• and a reactor which is connected to an output of the inverter,
• wherein the transformer, the inverter and the reactor are disposed inside of one housing,
• a flat heat exchanger which cools passing air with cooling water is disposed at a lower part inside the housing,
• the transformer and the inverter are disposed above the heat exchanger,
• the reactor is disposed above the transformer and the inverter,
• a protection panel is disposed further toward the front side of the housing than the transformer and the inverter by being separated from a front door of the housing,
• and by a fan which is provided at a position inside the front door, cooling air is circulated by passing through an air passage which is a space between the front door and the protection panel, a space between the heat exchanger and a bottom of the housing, the heat exchanger, the transformer and the inverter, the reactor and the fan, sequentially.
