摘要
An improved arrangement for extinguishing the inverter thyristors supplying current to an electric motor in which the output of the intermediate DC link supplying the inverter has placed across it two controlled rectifiers and a reversing choke along with a commutating capacitor connected in parallel with the reversing choke and one of the control rectifiers thereby permitting the motor current to be commutated even at operating speeds slightly above zero without the need for expensive circuitry.
