PURPOSE: A power supply device for an inverter is provided to prevent the malfunction of an electronic device by shutting down the inverter and reducing a driving device. CONSTITUTION: An inverter driving IC(102) determines whether a current operation voltage for power supply is within a preset reference operation voltage for power supply. A power supply unit(104) selectively provides a shutdown operation signal corresponding to the shutdown operation voltage if the current operation voltage for power supply is out of the reference operation voltage range. A shutdown circuit(106) shuts down an inverter by receiving the shutdown operation signal through the power supply unit. |
