Title:
ELECTRONIC POWER SWITCH DRIVE MODULE
Document Type and Number:
WIPO Patent Application WO/2019/166455
Kind Code:
A3
Abstract:
An electronic power switch drive module (2) for a power semiconductor unit (1), comprising a gate drive (6) and a current transducer (8) mounted on one or more circuit boards (4), the gate drive comprising at least one circuit portion (20) for controlling at least one transistor (13a) of a power semiconductor module (3) of said power semiconductor unit (1), the current transducer (8) configured to be coupled to an output (7) of the power semiconductor module (3) for measuring an output current of the power semiconductor module, said at least one circuit portion (20) connected to an output potential of the output current to be measured. The current transducer comprises at least one magnetic field sensor (16a, 16a', 16b), the current transducer being connected to said at least one circuit portion of the gate drive at said output potential in a non-isolated manner.
