Question:medium

The triggering pulses for 1-\(\phi\), full wave converter using Zero Crossing Detector, pulse amplifier and gate pulse isolation transformer, are obtained during

Show Hint

For negative-slope ramp synchronization: - Firing happens when the falling ramp crosses below the threshold: \( V_{\text{ramp}} < V_c \). - Raising \(V_c\) causes the intersection to happen earlier, which decreases the firing angle \(\alpha\) and increases the converter's output voltage.
