Title:
インバータ
Document Type and Number:
Japanese Patent JP2013511248
Kind Code:
A
Abstract:
An inverter, particularly for the energy supply of a three-phase motor (3) of a motor vehicle, where the inverter comprises a half bridge (1a, 1b, 1c) for electrically conductively connecting to the three-phase motor (3). The half-bridge (1a, 1b, 1c) comprises a voltage limiting element (8) which is electrically conductively connected to an input (6b) and an output (6c) of a power semiconductor switch (5a; 5b) of the half bridge (1a, 1b, 1c). The voltage limiting element creates, in a defined manner, a high impedance or low impedance connection between the input (6b) and the output (6c) of the power semiconductor switch (5a; 5b), depending on the voltage value of a voltage present between the input (6b) and the output (6c) of the power semiconductor switch (5a; 5b).
