DC power supply non-stop switching circuit using thyristor
Source: InternetPublisher:aerobotics Keywords: Thyristor DC power supply switching circuit BSP Updated: 2020/05/24
This circuit can
automatically start the backup power supply when the working power supply disappears to ensure uninterrupted power supply for electrical equipment
. The delay time of time relay KT is set at 1-2s.
The circuit is shown in Figure 14-122. When the grid voltage is normal, the load Rf: obtains DC power
from grid rectification and voltage stabilization . At the same time, the battery
GB is float charged. When the power grid fails, the thyristor is turned on and the load is powered by the battery GB.
