Abstract

The invention relates to a circuit arrangement (20) for an electrical converter (1) having switching units (15), each of which has a semiconductor switch (16) and a gate for controlling the semiconductor switch (16) drive circuit (17). The semiconductor switch (17) should be able to be switched particularly quickly by its corresponding gate drive circuit (17). To this end, in each switching unit (15), the semiconductor switch (16) and the gate drive circuit (17) are arranged on a common carrier circuit board (21), and the gate drive circuit (17) is passed through At least one conductor track (23) of the carrier circuit board (21) is electrically connected to the gate (G) of the semiconductor switch (16).

Description

technical field [0001] The invention relates to a circuit arrangement for an electrical converter. The circuit arrangement has a plurality of switching units, each of which has a semiconductor switch and a gate driver circuit for controlling the semiconductor switch. An electrical converter having a circuit arrangement according to the invention also belongs to the invention. Background technique [0002] In a converter for power electronics, the rectifier of the converter and / or the semiconductor switches of the inverter can be provided as modules. Such a module then has, for example, three half-bridges formed by semiconductor switches. To control the semiconductor switches, the module is connected to a separate circuit board on which the gate drive circuits of the semiconductor switches are implemented. The board is connected to the module at the control inputs by wires. Inside the module, the control input is connected to the gate of the semiconductor switch through b...
