  • Retrofitting DC Power Supplies and Rectifier Transformers
    NEELTRAN can help you replace ailing rectifiers and rectifier duty transformers that are placing your production at increased risk, without the headache of working with an engineering company or construction company. Nearly all Electrical Maintenance supervisors clearly understand how your DC Power
  • AC-DC Conversion
    In most power electronic applications, the power input is in the form of a 50 Hz or 60 Hz sine-wave AC voltage provided by the electric utility, which is then converted to a DC voltage. Increasingly, the trend is to convert the input AC into DC in an uncontrolled manner, using rectifiers and diodes
  • Supplying an AC/DC Power Supply
    to work from 100VAC to 240VAC) or fixed input AC/DC supplies (designed to work at 115VAC or 230VAC) will probably work with a DC input and the only difference in operation would be that only two of the diodes forming the bridge rectifier would be utilised. A linear power supply that has a transformer
  • Combined DC Power Supply Testing
    NEELTRAN's unique ability to perform Combined Testing on Rectifier Transformers and hi current DC Rectifier systems offers advantages including reduced risk, lower costs, and time savings to customers. NEELTRAN's ability to perform combined testing on its Industrial DC Power Supplies means
  • Custom DC Power Supplies for Aluminum Smelters
    NEELTRAN makes a big difference by being one of the few transformer/rectifier manufacturers that can adopt a flexible design approach for every industrial power conversion project (designing reliable DC Power Supplies -- Rectifier Transformers and Rectifiers). NEELTRAN has earned a reputation
  • Regeneration vs. Dynamic Braking in DC Drives
    are in a DC phase controlled drive. Regeneration in a phase controlled DC drive involves a second (antiparellel connected) rectifier bridge. During regeneration, mechanical energy from the rotating load and armature (now acting as a generator), is inverted from DC directly back onto the AC power line
  • Brushless DC Motor Control Using PIC18FXX31 MCUs
    A PICDEM TM MC demo board was used to develop, test and debug the motor control code. The PICDEM MC has a single-phase diode bridge rectifier, converting AC input to DC and a power capacitor bank that keeps a stable DC bus. A 3-phase IGBT-based inverter bridge is used to control the output voltage
  • An Improved Active Front End Non- Regenerative Rectifier System Employing a Five-Limb Inductor
    to be helpful in limiting non characteristic harmonics. Since the current injected into the split dc bus capacitor is a 360Hz ripple, it is proposed that the main dc bus capacitor be split into film capacitor for ripple current and optimally reduced electrolytic capacitor for the main energy storage
