Title:
INVERTER APPARATUS
Document Type and Number:
Japanese Patent JP3473276
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To prevent the load for an inverter apparatus from being an electrical noise source or a leakage current source even if the load is a resistor.
SOLUTION: A DC power supply 5 is inputted to an inverter apparatus 1. The output of the inverter apparatus 1 is converted by turning on/off switch devices in a converter 2 in accordance with the signal of a control unit 3 which outputs the signal following the command of an operation unit 4. By providing a power supply output unit which is connected to the plus side or minus side of the DC power supply 5, not an AC current but a DC current can be applied to a resitor load 6 which is connected between the power supply output unit and a switching output unit. As it is not necessary to generate an AC waveform from a DC current and a carrier is not necessary, the intermittent output of DC or low frequency can be outputted, so that harmonic current components can be eliminated.
