摘要 |
<p>For starting a shut down inverter with the correct phase with a likewise shut down control unit, start control logic is provided, which is addressed by a signal imaging the phase of the monitored system voltage. The start control logic contains a memory for the phase of the system at the time of a disturbance. Upon a start command, the control unit is made to deliver firing pulses in such a manner that the output voltage of the inverter begins with the stored phase of the system at the instant of the disturbance. Preferably, the oscillator of the control unit is started with the stored phase.</p> |
