Driving apparatus of H bridge circuit and protection method of the same |
摘要 |
In order to protect semiconductor switching-devices employed in an H bridge circuit against an over-voltage without using a special protection circuit, a control circuit outputs a control signal to a driving circuit for driving the H bridge circuit in order to turn off FETs serving as the semiconductor switching-devices when an over-voltage detection circuit detects the over-voltage applied to the H bridge circuit.
