A welding machine including analog synthesizing part and voltage balancing part

摘要

The present invention provides an input unit to which an input signal is input by a user, a noise generating unit generating interference noise by operation, a sensor unit disposed adjacent to the noise generating unit to measure the interference noise generated by the noise generating unit, and active noise The central control unit that controls the sensor unit, active noise control unit, and feedback unit to perform active noise control (ANC), is electrically connected to the central control unit, Active noise control unit that emits noise, a feedback unit that detects the actual noise generated from the facility and extracts an analog actual noise signal for the actual noise, and is electrically connected to the feedback unit to generate a synthetic signal that synthesizes the analog actual noise signal into an analog signal and a voltage distribution unit that is electrically connected to the analog signal synthesis unit and the analog signal synthesis unit to generate a distribution signal obtained by dividing the size of the synthesized signal and transmits it to the active noise control unit, and the voltage division unit distributes the actual noise as the distribution signal is generated To provide an active noise control system using an analog signal synthesis unit and a voltage divider, characterized in that the attenuation by
