The Agilent HP 6428B utilizes silicon-controlled rectifiers in series with the transformer primary. Controlled by the output voltage and current settings, these supplies accomplish the desired regulation using a ramp-lock phase control circuit. This circuit technique permits a reduction in the overall size and weight of the power supply and results in up to 75 efficiencies at full output.
