Battery DC panel uninterrupted power supply conversion circuit
Source: InternetPublisher:D先生 Keywords: DC panel battery conversion circuit power supply Updated: 2021/05/10
Battery DC panels are widely used in DC systems of power plants and substations. In order to make the DC system operate more safely and reliably
, the uninterrupted power supply conversion circuit as shown in the figure can be used. The uninterrupted power supply conversion circuit
is composed of thyristor V, voltage regulator VS and resistor R. When the AC 380V power supply is normal
, VS is cut off and V is turned off. When the AC 380V power supply is interrupted or the output voltage of the floating charger Ul drops or disappears due to a fault
, vs breaks down, V is turned on, and the battery GB immediately supplies power to the control bus wc .
