Title:

EQUALISATION CIRCUIT, DEVICE TO BE CHARGED, AND CHARGING CONTROL METHOD

Document Type and Number:

WIPO Patent Application WO/2018/152786

Kind Code:

A1

Abstract:

An equalisation circuit, a device to be charged, and a charging control method. The equalisation circuit (33) comprises: a first conversion unit (331), used for receiving a direct current voltage outputted by a first chip (131) and converting the direct current voltage outputted by the first chip into a first alternating current voltage; a first resonance unit (332) used for receiving the first alternating current voltage and converting the first alternating current voltage into a second alternating current voltage using a resonance method, the amplitude of the second alternating current voltage being greater than the amplitude of the first alternating current voltage; a first capacitive coupling unit (333) and a second conversion unit (334), the first capacitive coupling unit coupling the second alternating current voltage to the second conversion unit by means of a capacitive coupling method, and the second conversion unit converting the second alternating current voltage into a first charging voltage for charging a second chip (132).
