METHOD AND APPARATUS FOR CURRENT/POWER BALANCING

摘要

Aspects of the disclosure provide a power circuit that includes a first switch module and a second switch module in parallel. The first switch module has a first gate terminal, a first drain terminal and a first source terminal, and the second switch module has a second gate terminal, a second drain terminal and a second source terminal. A drain interconnection module coupled to the first drain terminal and a gate interconnection module coupled to the second gate terminal are inductively coupled to balance current flowing through the first switch module and the second switch module.
