Direct converter with a frequency-dependent current limit |
摘要 |
In order to protect a direct converter, formed from thyristor converters, against thermal overload, a device is provided which, at low frequencies, limits the amplitude of the current supply variable provided for controlling the converter, and, by means of the reference variable, does not enable the maximum current amplitude in accordance with the design of the converter below a minimum frequency (fmin). <IMAGE>
