Title:
VOLTAGE CONTROL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2014/030259
Kind Code:
A1
Abstract:
Provided is a voltage control apparatus that can step up the voltage of an inputted polyphase alternating current and stably supply high voltage. The voltage control apparatus (10) is provided with: a zero-crossing detection means (20) that measures zero-crossing points of a three-phase AC voltage; a voltage adjustment means (50) that gives instructions to connect the phase in which a zero-crossing point is detected, phase T for example, to phase R having the same polarity as phase T; and an inter-phase connection means (60) that connects each of the phases with each other according to instructions from the voltage adjustment means (50). The voltage adjustment means (50) starts inter-phase connections from the zero-crossing points or from points in time obtained by shifting a phase angle from the zero-crossing points and determine the starting time, period length, and shift amount for inter-phase connection periods by executing PID control while monitoring the voltage measured by a voltage measurement means (30).
