Title:
AC POWER REGULATOR AND AC POWER CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2017/169084
Kind Code:
A1
Abstract:
An AC power regulator controlling power supply to a load by using phase control, that: calculates an estimated output power value on the basis of preset voltage information for a power supply connected to the load and on the basis of a measurement value for current that flows to the load; and performs simulated constant power control, on the basis of the difference between this estimated output power value and a target power value (the product of an applied target load factor and a preset maximum target power value). As a result, an AC power regulator can be obtained that has reduced cost, is more compact, and, even for a load having resistance value fluctuation as a result of deterioration over time, etc., can perform control that follows this fluctuation.
