Principles of Operation

Autoranging Power

Autoranging allows the unit to be compact and light weight and yet to deliver a range of output voltage/current combinations which would otherwise require the use of more than one supply or a higher rated power supply. Autoranging is a name for circuitry which automatically makes full power available at all but low rated output voltages and currents. By comparison, a conventional constant voltage/constant current (CV/CC) power supply can provide full output power only at maximum rated output voltage and current.

Overview

The Simplified Schematic, Figure 4-1, shows how the major circuits are connected. Segmenting the Simplified schematic into functional circuit blocks will highlight how these blocks work and illustrate overall system function.

Table 4-1 briefly describes the major circuits employed in the design of this unit. When used in conjunction with the Simplified Schematic, the reader is provided with a quick overall appreciation of the unit's operation.

Power flows from the ac mains at the left of the schematic through circuit blocks connected by heavy lines to the output terminals at the right. Follow the schematic from right to left to see how the output voltage is regulated during CV mode of operation, The output voltage is monitored both at the output sense terminals + S and - S; OVS (Outerloop Voltage Sense) and also before the two stages of output filter IVS (InnerLoop Voltage Sense).

Sensing with output sense terminals provides accurate load-voltage control and sensing before the output filter stabilizes the supply and permits it to power reactive loads. The CV monitor amplifier buffers the OVS voltage to produce the V-MON output monitoring voltage. A buffer amplifier monitors the voltage before the output filter to produce the IVS voltage.

When in CC operation, the output current is regulated in a similar manner. Output current is sensed as the OCS outerloop voltage across a current monitoring resistor. OCS is buffered to produce l-MON. IVS is differentiated to produce an innerloop current sensing voltage.

System Description

The Agilent 6010A /6011A/6012B/6015A are power supplies which utilizes the principle of switching to achieve regulation. Basically, the power supply employs five major functional sub-systems together with the Front Panel to achieve its overall objective of delivering a maximum of 17A or 200V (6010A); 120A or 20V (6011A); 50A or 60V (6012B); 5A or 500V (6015B), at the power output of 1000W.

These sub-systems are
