Multiple asynchronous rectifier machines - are operated by LC filter on mains side controlling pulse current rectifier input voltage |
摘要 |
<p>Torque and speed of the asynchronous rectifier machines are controlled, and the machines are supplied from the mains through a rectifier unit consisting of a pulse current rectifier and phase sequence rectifier with impressed intermediate circuit current. Input voltage (Uc) of the pulse current rectifier can be controlled within a freely selectable sinusoidal tolerance band using a filter (Li, C) on the main side. The single phase network has a transformer (T) on the main's side and has the pulse current rectifier (PSR) connected with a phase following rectifier (PFSR) on the secondary side. A number of measured value converters (MUuO) are connected to tappings at various stages in the circuit.</p> |
