| 2.00 | Supply and fixing in repair of DC Control PCB –
DC voltage of the AC-DC converter is regulated by sensing DC output voltage through a chain of program resistors and current control loop in the Converter control PCB2 (EE-27M3). In case mains input varies or current drawn by Inverter varies, the command voltage of the control loop varies such that output voltage of AC – DC converter is kept constant. The firing PCB1 (EE-28), provides the required drive & firing pulses to the six SCRs, so as to achieve voltage control. The power supply is generated from transformer of part No T17 of OEM complete all as directed by Engineer in Charge. | 15 | Each | 10,000 ₹1,50,000 Lowest | 13,000 ₹1,95,000 |
| 3.00 | Supply and fixing in repair of DC Firing Control PCB
This circuit generates six gate drive pulses to control firing of SCRs of AC Voltage Regulator. This circuit is part of Charger Control PCB1 (EE-28). The DC power supply required for firing and control circuit is derived from mains sensing and power supply transformer (T2A, T2B, and T2C). These transformers sense mains zero voltage instant. The firing instant of SCRs is advanced or retarded by DC voltage command signal given to the firing circuit. This circuit acts as an interface between full controlled Rectifier and control circuits complete all as directed by Engineer in Charge. | 17 | Each | 10,000 ₹1,70,000 Lowest | 18,000 ₹3,06,000 |

| 6.00 | Supply and fixing in repair of Inverter Control PCB
PWM INVERTER CONTROL CARD (PCB –9A, 9B, 9C) (EE- 09 BM2)
The main function of PWM Inverter Control card (EE-09A, EE-09B, EE-09C) is to generate PWM pulses for IGBT Inverter Bridge of each phase, control the output voltage within acceptable limits, protect SFC from output over load, output over voltage, output under voltage, output short circuit and over temperature of power IGBTs.
The output voltage of the Inverter is sensed from each output phase by Inverter feedback transformers (T12A, T12B, T12C) and fed to output voltage control loop. In case DC input voltage to the Inverter or load on the Inverter varies, this voltage loop controls modulation such that Inverter output voltage remains constant. Non-linear load or introduction of dead band between the two PWM waveforms may introduce some distortion at the output voltage of the Inverter. This distortion is corrected by a waveform correction circuit in the control card. (EE-09B)
The output current is sensed by output current feedback transformers CT2A, CT2B, CT2C. | 20 | Each | 19,000 ₹3,80,000 | 15,000 ₹3,00,000 Lowest |
| 7.00 | Supply and fixing in repair of Control Transformer of part No 22 of OEM
The electronic power supply required for DC Firing Control PCB is generated from this transformer T22. The synchronizing signal required for firing instance for Semi pack is also generated by these transformer complete all as directed by Engineer in Charge. | 28 | Each | 2,700 ₹75,600 | 1,500 ₹42,000 Lowest |
| 8.00 | Supply and fixing in repair of Driver PCB
IGBT DRIVER AND TRIP CIRCUIT (PCB – 8A1, 8A2, 8B1, 8B2, 8C1, 8C2) (EE-08M1)
The PWM waveforms generated by control circuit are fed to two driver PCBs (EE-08M1) for driving IGBT bridge of each phase (Driver PCB 8A1, 8A2, 8B1, 8B2, 8C1, 8C2). Each driver circuit drives half bridge and ensures that IGBT are in saturation when turned ON and fully turned OFF by reverse biasing when control drive is off. If any transistor tends to go out of saturation due to excessive overload or inadequate base drive, it cuts off base drive from the IGBT and trips the Inverter through Inverter trip circuits EE-08M1 complete all as directed by Engineer in Charge. | 25 | Each | 5,700 ₹1,42,500 | 4,000 ₹1,00,000 Lowest |
| 9.00 | Supply and fixing in repair of Power IGBT
This is the main power component used for conversion of DC voltage, generated by AC to DC converter, to 400 Hz AC supply of desired voltage. This is most important component in this SFC. There are Six IGBT modules in each SFC for 3 phase SFC and two IGBT modules for single phase SFC. Each IGBT module consists of two IGBTs connected in series and connected across the controlled DC voltage. The IGBTs are switched ON and OFF through IGBT Driver PCBs. IGBTs are selected as per power rating of the SFC complete all as directed by Engineer in Charge. | 25 | Each | 5,050 ₹1,26,250 | 4,000 ₹1,00,000 Lowest |
