PURPOSE: A current supply apparatus for conveyors is provided to be used as a power source for various motor-driven apparatuses outside where no alternating source is available. CONSTITUTION: A current supply apparatus for conveyors includes an inverter(110), a transformer(120), and an LC circuit(140). The inverter includes a pair of transistors(111,112), whose emitters are connected to an input node in parallel, to convert a direct current source to an alternating current source. The transformer steps up a voltage source converted to an alternating current to a commercial voltage of 220 V. Collectors of the transistor in the inverter are coupled with the transformer. The LC circuit suppresses harmonics from the result of the transformer and outputs clean sinusoidal waves.
