PURPOSE: An inverter is provided to secure the safety of a system by stably connecting a second input unit to a system through a system protection unit. CONSTITUTION: A first input unit(210) receives an input voltage, a first reference voltage, and a plurality of signals. A second input unit(220) is connected to the first input unit. The second input unit receives the input voltage, the first reference voltage, and the second reference voltage. A system protection unit(230) is connected to the first and second input units and includes a first switching unit, a voltage distribution unit, and a second switching unit. The first switching unit controls a second reference voltage. The voltage distribution unit controls the distribution of the input voltage according to the supply or cutoff of the second reference voltage. The second switching unit operates according to the input voltage distributed by the voltage distribution unit or the second reference voltage controlled by the first switching unit. |
