1.0 GENERAL INFORMATION 1.1 Description This manual contains operation and maintenance instructions for Magna-Power Electronics' XR Series, current fed power supplies. These power supplies are constant voltage/constant current sources suitable for a wide range of applications. 1.2 Features Magna-Power Electronics’ XR Series combines the best of dc power processing with multiprocessor embedded control.
PAGE 14
XR Series power supplies have three levels of over voltage/current protection: shutdown of controlling insulated gate bipolar transistors (IGBT’s), disconnect of main power, and input fuses. After an over voltage/current trip condition, the supply must be reset. XR Series power supplies have push button start/stop controls. These controls are tied to a mechanical contactor which operates with the electronic switches to break the ac mains when stop is commanded.
PAGE 15
Table 1.
PAGE 16
XR Series models have extensive diagnostic functions -- all of which when activated take command to shut down the system. Diagnostic functions include phase loss, excessive thermal conditions, over voltage trip, over current trip, and program line. Program line monitors externally applied analog set point signals to insure they are within the specified range. Upon a diagnostic fault condition, main power is disconnected and the diagnostic condition is latched into memory.

3.4.1 Resistive Programming Resistive programming requires connection of an external potentiometer or resistors between terminals 21, 3, and 1 of JS1. Terminal 21 is a 10.0 V precision reference, terminal 1 is the reference ground, and terminal 3 is the voltage set point input. Like front panel rotary control, the precision reference produces a voltage across the potentiometer or resistors which is then used to produce the voltage set point.

and the power supply will turn off. 3.4.3 Current Programming Current programming, like voltage programming, does not require the voltage reference at terminal 21 of JS1. To produce the voltage reference, a current source is applied to a shunt resistor. Using a 2 mA current source, place a 10.0 K precision metal film resistor between terminals 1 and 3 of JS1. The input impedance between terminals 1 and 3 is 10K and paralleling the additional resistor produces an equivalent resistance of 5K.

4.0 PROGRAMMING WITH SCPI COMMANDS 4.1 Command Features XR Series power supplies provide RS232 communications as a standard feature and IEEE-488 or Ethernet communications as an optional feature. A second UART port, a factory installed option, is enabled after power on by recognizing which port is receiving communications. Once a particular port has been activated, the other UART port cannot be recognized unless there has been a period of inactivity for 5 minutes.

Start the HyperTerminal test software and set the COM port to the one connected to the XR Series power supply. Configure the terminal for 19200, N, 8, 1. Set the terminal to echo typed characters locally and “append line feeds to incoming line ends.” (The echo feature is not functional with Windows 98.

Figure 4.1 RS232 Communications using Microsoft Windows (tm) HyperTerminal 4.3.1.1 VOLT and VOLT:TRIG These commands set the immediate voltage level or the pending triggered voltage level of the power supply. The immediate level is the voltage programmed for the power supply output. The pending triggered level is a stored voltage value that is transferred to the power supply when a trigger occurs.

pending triggered level is a stored current value that is transferred to the power supply output when a trigger occurs. A pending triggered level is unaffected by subsequent CURR commands and remains in effect until the trigger subsystem receives a trigger or is aborted with an ABORt command. In order for CURR:TRIG to be executed, the trigger subsystem must be initiated (see INITiate). CURR? and CURR:TRIG? return presently programmed immediate and triggered levels.

6.0 PRINCIPLE OF OPERATION Power is fed through ac fuses and is distributed to the auxiliary power supply, inrush limiter, and main 3φ contactor. The auxiliary power supply operates off the ac mains supplies power to the other printed circuit boards in the system. The inrush limiter is a step start device which is used to initially charge capacitors on the input dc bus and limit the inrush of current. The inrush limiter is initiated when the power supply is switched from a standby to a power state.

The phase detector senses input line voltage on each phase. Upon detection of a problem, the control board is signaled to shutdown the system. The control board, which is referenced to earth ground, contains optically isolated amplifiers to sense output voltage and current. This circuitry allows the output to be referenced ±1000 Vdc above earth ground. The display board contains light-emitting diodes for displaying diagnostic conditions and provides an interface for meters and switches.

7.0 MAINTENANCE AND TROUBLE SHOOTING 7.1 General The XR Series power supplies consist of a multistage power processing system. Because of its complexity, it is highly recommended that all repairs be performed by the factory or qualified power supply technician. Before attempting maintenance or repair, the technician should be familiar with the components of the systems and the theory of operation.
PAGE 108
7.3 Calibration 7.3.1 Control Board The control board contains digital potentiometers for fine adjustments of the reference and feedback amplifiers. These potentiometers may be adjusted by using the front panel controls described in Section 3.1.4. These potentiometers can also be adjusted by using the Calibration Panel of the Remote Interface Software described in Section 5.5. 7.3.1.
PAGE 109
7.3.2.1 Over Current Protection Over current protection should only be calibrated after consultation with the factory. Gross misadjustment can cause chopper and inverter failure. Place a dc voltmeter between test point TP6 (positive) and test point TP7 (negative). With only the control power applied, adjust potentiometer P1 to 6.00 V. 7.3.2.2 Under Voltage Protection Under voltage protection should only be calibrated after consultation with the factory.

8.3 illustrates the different charging steps and Table 8.4 provides the recommended charging voltage per cell for different battery technologies. Diode D1 with associated remote sense connections can be avoided with application of the highslew rate option. As compared to standard XR Series models, the high-slew rate option has less output capacitance and less loading on the battery when the power supply is off. Appendix 8.6 discusses the benefits of this option.

8.6 High-Slew Rate Option The standard output stage of XR Series power supplies has been designed to provide the lowest possible output ripple voltage within the constraints of available components, size, and cost. Part of the output stage consists of a bank of aluminum electrolytic capacitors which has the desired electrical properties to provide this function. These components require bleed resistors to discharge any voltage when the power supply has no load and is disabled.
