REFRIGERATOR INVERTER DEVICE

摘要

PURPOSE: A refrigerator inverter is provided to prevent an over current by restricting a short taking place when transistors are turned on at the same time. CONSTITUTION: The refrigerator inverter(80) device comprises; a power source part(70) to supply power; an inverter to generate a 3 phase electric power by switching the power supplied by the power source part(70) using transistors; a control part to generate switching signals and pulse modulating signals of each transistor of the inverter; a brushless DC motor compressor driven by the 3 phase electric power generated by the inverter; a position sensor to sense the rotor position of the brushless DC motor compressor.
