Abstract

A power semiconductor module integrating a Hall current sensor, comprising an output electrode, a sampling control terminal, a bottom plate, a ceramic substrate, and a casing, the output electrode is connected to an output electrode arm arranged parallel to the direction of the bottom plate, and the output electrode arm is connected to the ceramic The substrates are connected, the output electrode arm is covered with a sensor core, the sensor core has an upward core opening, and a Hall element with pins facing upward is inserted into the core opening; the shell An insertion hole is provided at a corresponding position above the opening of the magnetic core, and pins of the Hall element pass through the insertion hole. The invention integrates the current sensor inside the power semiconductor module, increases the integration degree, miniaturization degree and stability of the control system, and reduces the subsequent use cost.

Description

technical field [0001] The invention relates to the field of power electronics, in particular to a power semiconductor module integrating a Hall current sensor. Background technique [0002] The power module is a power switch module packaged by power electronic power devices such as metal oxide semiconductor (power MOS tube), insulated gate field effect transistor (IGBT), and fast recovery diode (FRD) according to certain functions. It is mainly used for Power conversion in various occasions such as electric vehicles, photovoltaic power generation, wind power generation, and industrial frequency conversion. The topological structure of the power semiconductor module is single-tube, two-unit, six-unit, etc., and can be combined into half-bridge, three-phase full-bridge and other circuit forms according to needs. In actual use, it is often necessary to obtain the output current value. [0003] A defect of the traditional power semiconductor module is that it does not have th...
