1. An apparatus for wireless power transmission, the apparatus comprising:
- a power device;
an overvoltage protecting unit and an overcurrent protecting unit configured to protect the power device; and
a control unit configured to perform an operation on an output signal of the overvoltage protecting unit and an output signal of the overcurrent protecting unit, and determine whether an input signal is transmitted to the power device in response to an operation result.

Abstract
An overvoltage protecting unit and an overcurrent protecting unit protect a power device from an overvoltage and an overcurrent using a comparator having hysteresis. An overtemperature protecting unit protects the power device from an overtemperature using a thermistor having a resistance that changes as a temperature of the thermistor changes.
