Beschreibung
Zusammenfassung:	A power conversion device according to an embodiment includes: a voltage regulator circuit configured to regulate power from a power source to a desired voltage; an inverter configured to convert the power output from the voltage regulator circuit into an alternate current power; a resonant circuit having inductance and capacitance; a high frequency transformer configured to convert the alternate current power of the inverter; a rectifier configured to convert the alternate current power output from the high frequency transformer into a direct current power; a temperature detector configured to detect a temperature of the resonant circuit; and a controller configured to detect an anomalous resonant frequency when the temperature is equal to or higher than a predetermined temperature threshold to control an anomalous state.
