Abstract
An electronic apparatus having a load including: a power supply unit supplying a driving voltage to the load; an inverter unit switching the driving voltage; and a control voltage supply unit outputting a first control voltage lower than a reference voltage applied to one terminal of the inverter unit, and a second control voltage higher than the reference voltage, thus controlling the inverter unit. Thus, the electronic apparatus and power circuit are capable of improving a control voltage applied to an inverter unit to reduce the switching loss of the inverter unit.
