Title:
POWER CONVERTER CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/203113
Kind Code:
A1
Abstract:
Provided is a control device (30) applied to a power converter (100) for converting one voltage of an AC voltage and an inter-terminal voltage of a capacitor that is input to the power converter (100) into the other voltage. The control device (30) calculates a command value for a sinusoidal reactor current on the basis of the AC voltage and an amplitude command value indicative of the amplitude of the reactor current. Additionally, the control device (30) performs peak current mode control to operate a switch SW in order to control the reactor current to a command value for the reactor current resulting from addition of a current correction value. The control device (30) sets, on the basis of an AC voltage Vac, the current correction value to a value including a variation component of the inter-terminal voltage of a capacitor 16.
