Webbregulated to provide (0-15V) DC to the gate of SCR. * The gate current adjustment can be made using the coarse and fine adjustment POT. Switch (SW1) controls the VDC1 input voltage. * Ammeter between P5 and P7 is to read the gate current (I g). Ammeter between P8 and P11 is to read the device current (IA). Webbholding current is less than maximum value (150 mA, typical value of 30 mA to 65 mA). The switching current (I S) is very near the holding current (I H) value. When the SIDAC switches, currents of 10 A to 100 A are easily developed by discharging small capacitor into primary or small, very high-voltage transformers for 10 µs to 20 µs. razor page redirect to loginWebb21 maj 2024 · Alternatively, the SCR can be put into the forward conduction mode by applying the gate that will increase the anode current above the latching current.
