Protection Circuit of inverter in Railway Vehicle. In order to prevent an unacceptable blockade Voltage Thyristors are connected in parallel with a Resistance Member (9) - Condenser - resistance, and the circuit has a Secure (2) for the disconnection in the event of excessive current.Each Thyristor are connected with a Resistance (13) and a blocking Diode decoupling (19).The central point of this combination (13, 19) is connected via a Diode (15) scale with the Grid Control for Thyristor (9), in which the secondary inverter Voltage decreases in the case of a breakdown by overvoltage with TENS Ion of the blockade, and the Inverter is switched on via the voltage.
