Arrangement for testing a power output stage |
摘要 |
The invention concerns a device for controlling a final power-output stage, the latter comprising three half-bridges consisting respectively of a series circuit including an upper semiconductor switch and a lower semiconductor switch and subjected to a service voltage, the connection points of the semiconductor switches of the half-bridges forming outputs which are connected to the windings of a motor having at least three phases. The invention is characterized in that there is provided a control device for shifting on-state respectively one semiconductor switch or simultaneously several semiconductor switches according to a predetermined programme and for determining whether the respective voltages at the outputs are respectively within a predetermined tolerance range for the corresponding switching state.
