VOLTAGE BALANCING CIRCUIT, AND SWITCH ELEMENT STACKING CIRCUIT COMPRISING SAME

Document Type and Number:

WIPO Patent Application WO/2024/085300

Kind Code:

A1

Abstract:

The present invention relates to a voltage balancing circuit, and a switch element stacking circuit comprising same, and more specifically, to a voltage balancing circuit, which maintains a voltage balance between a plurality of switch elements connected in series, and a switch element stacking circuit comprising the voltage balancing circuit, wherein the switch element stacking circuit generates high voltage pulses. Disclosed is a voltage balancing circuit (600) for the voltage balancing of a switch module (100) comprising a plurality of switch elements (S1, ..., SN, N is a natural number of 2 or more) connected in series, the voltage balancing circuit (600) being characterized by comprising: a plurality of primary balancing units (B1, ..., BN) which are installed in correspondence with the plurality of switch elements (S1, ..., SN), respectively, and connected in parallel to the switch elements (S1, ..., SN); and a plurality of secondary balancing units (B2_1, ..., B2_N) which are mutually inductively coupled in correspondence with the plurality of first balancing units (B1_1, ..., B1_N), respectively, wherein the secondary balancing units (B2_1, …, B2_N) are electrically connected to other secondary balancing units (B2_1, …, B2_N).
