Title:
AC POWER CONDITIONER
Document Type and Number:
WIPO Patent Application WO/2018/047290
Kind Code:
A1
Abstract:
Provided is an AC power conditioner that includes a function by which control of the supply of power to a load is carried out by phase control, and the effective value of output voltage or output current supplied to the load is measured, wherein the effective value of an output voltage or output current value is more accurately measured, as a result of the provision of the following: a measurement unit that measures, at a prescribed sampling timing, the instantaneous value of output voltage or output current supplied to the load; an effective value calculation unit that calculates the effective value of the output voltage or output current on the basis of the measured instantaneous value; and a correction unit that corrects a difference which is based on the deviation between a trigger point in phase control and a sampling point for measuring the instantaneous value.
