Document Type and Number:
WIPO Patent Application WO/2013/094822
Kind Code:
A1
Abstract:
The present invention includes an input-side transient phenomena suppressing unit that is connected to a power supply and a load facility in parallel and suppresses an over-voltage and an over-current supplied from the power supply, an input-side wave filter that is serially connected between the power supply and the load facility and filters a high frequency output from the input-side transient phenomena suppressing unit, an in-phase removing transformer that is serially connected between the power supply and the load facility and removes in-phase components of each of a power line and a neutral line from the input-side wave filter, an output-side filter that is serially connected between the power supply and the load facility and filters a high frequency output from the in-phase removing transformer, and an output-side transient phenomena suppressing unit that is connected between the power supply and the load facility in parallel and suppresses an over-voltage and an over-current supplied from the output-side filter to the load facility.
