DS200DCFBG2B is a Power Supply Board manufactured and designed by General Electric as part of the DC2000, CB2000, EX2000, FC2000, GF2000, ME2000, and AC2000 Series used in IGBT drive applications. The board is put to a different use by the EX2000 than it is by a drive. Italics in parentheses are used to indicate information that is different for the EX2000 applications. The DS200DCFB Power Supply Board (DCFB) supplies control-level power to the drive and 115 V ac power (NA) to the enclosure fans by receiving 38 and 115 V ac (24 V dc) input power from the control power transformer (CPT). The following circuits are present on the DCFB board:

The DS200DCFB Power Supply Board (DCFB) supplies control-level power to the drive and 115 V ac power (NA) to the enclosure fans by receiving 38 and 115 V ac (24 V dc) input power from the control power transformer (CPT). The following circuits are present on the DCFB board:

− Armature current(s) and voltage(s) (NA)
− Motor field currents (NA)
− Ac line current
− Ac line voltage magnitude and phase sequence


  • The CPT gives the DCFB board 38 V ac or around 10%. (24 V dc). For the unregulated 24 V dc outputs, this voltage is full-wave rectified and filtered. The outputs at +24 V and -24 V are both rated at 3 A and 1 A, respectively.
  • The DCFB board's regulators draw 15 V dc from the 24 V dc sources. Each of the 15 V dc outputs is capable of handling 0.8 A, of which 0.25 A can be used for external loading.
  • The +24 V dc supply is used by the DCFB board to produce a +5 V dc, 4 A output as well. When the +5 V dc supply is regulated, the /PSEN signal on 2PL enters a TTL low state. If the +5 V dc supply is not regulated, the signal enters a high state. When set to high, /PSEN causes the Drive Control Card's microprocessor to reset.
  • The armature current feedback circuits are powered by isolated +5 and 15 V dc supplies from the DCFB board.
  • Fuse numbers FU2 and FU3 guard against short circuits at the power supply outputs (7 A, 2AG). For these fuses, blown fuse indication is provided by light-emitting diodes (LEDs) CR51 and CR55. Fuse FU1 (1/2 A, 2AG) guards the 115 V ac output.


Voltage-controlled oscillator (VCO) circuits on the DCFB board transform input voltages into frequency signals. The nominal output frequency of each VCO is 250 kHz. Depending on the input voltage, the output frequency ranges from 0 to 500 kHz. Via connection 1PL, VCO outputs are transmitted to the SDCC/LDCC board to provide the following feedback:

  • SCR bridge ac input voltage
  • Output bridge voltage
  • Motor voltage (NA)
  • Millivolt signals from field shunts
  • Millivolt signals from armature shunts

The SDCC/LDCC board receives feedback from the output bridge VCO circuit at connector 1PL, pin 13. (1PL- 13). To scale the voltage provided to the circuit, DIP switch SW4 is employed. A diagnostic signal for test point TP37 on the SDCC/LDCC board is delivered through 1PL-37 by a frequency-to-voltage reconstruction circuit. With an ac-coupled oscilloscope, the diagnostic bridge voltage signal can be seen. Via 1PL-39, the second VCO transmits feedback about the motor voltage to the SDCC/LDCC board. To scale the voltage applied to the circuit, use the DIP switch SW5.
