In fact, the control of voltage is a major issue in power system operation. 1(b) and the power transformer work together to compensate the voltage sags and swells. The added circuitry allows users to control the buck converter's output voltage, V Out, in the range of 0 to 5 V with a control voltage, V C, in the range of 0 to 2. Control voltage - How is Control voltage abbreviated? which will be used for generating the control voltage. Recently, however, some companies reverted back to voltage-mode control when complications arose in implementing current-mode control. Countermeasures for Surge Voltage of Relay Control Transistor If the coil current is suddenly interrupted, a sudden high voltage pulse is developed in the coil.
