  • Page 28 Wayne Kerr AP 1kW Power Supplies • Issue 2 a) Limitations The maximum voltage allowed between the output and earth is 200V d.c. This limits the number of units that can be connected in series. For the AP6050, up to 3 units can be operated over their full range, uni-polar with respect to ground, and 6 units for centre- tapped bipolar operation.
  • Page 29 Wayne Kerr AP 1kW Power Supplies • Issue 2 To maintain the temperature coefficient and stability specifications of the supplies, the ° external resistors should be low noise and low temperature coefficient (50ppm per types. When choosing resistor values, a compromise has to be found between programming speed (which is impaired when the source impedance of the voltage programming sources is greater than a few kΩ) and resistor dissipation (which increases with lower...

  • Page 31: Current Monitor (Imon )

    Wayne Kerr AP 1kW Power Supplies • Issue 2 6.6. Current Monitor (I mon ) The current monitor (terminal 2) output provides a signal which is the amplified voltage developed across the current sense resistors. This signal is used for parallel operation but can also be used to monitor the output current.

  • Page 32: Circuit Description

    General Although specific to the AP6050, the following describes, in general, the AP3080 and AP10030 versions. Minor variations may occur between the different units. Reference is made to a number of diagrams. These are the schematic (giving major components and circuit function), the control board, the front panel board, the power conversion and a connection diagram.
  • Page 33 Wayne Kerr AP 1kW Power Supplies • Issue 2 (control board diagram). This allows for a more precise control of the width of the narrow pulses which are needed when a very low power output is demanded. When this ramp reaches a value determined by the voltage on pin 9 of the comparator, IC2-C (control board diagram), the drive pulse is switched off.
  • Page 34 Wayne Kerr AP 1kW Power Supplies • Issue 2 pin 2 of IC15 goes more positive than pin 3, the output of IC15 goes negative and takes command of the voltage controlling the ramp comparator. This results from the action of the OR gate formed by D30 and D31 which selects the lower of the output voltages from the voltage and the current comparators.
  • Page 35 Wayne Kerr AP 1kW Power Supplies • Issue 2 Displays & Metering Current and voltage monitoring is by digital displays and bargraphs. Voltages proportional to output current and voltage are fed to the meter circuits via analogue switches IC18, IC20 and IC25 and buffer amplifiers IC19-B and IC24-C. The analogue switches switch the voltage derived from the output voltage and current (when the enable switch is on), or the output voltage and current settings (when the enable switch is off).
