Leave a comment

Type-I : Thyristor Based Battery Charger  

tbh-i

  • Long operational life more than 20 years.
  • Robust operation
  • Easy for troubleshooting

SCR Firing techniques

  • 6 Pulse
  • 12 Pulse
  • 24 Pulse

Advantages: 12 & 24 Pulse Chargers

  • Very low ripple factor
  • Minimized Harmonic Distortion
  • Improved Power Factor
  • Higher Efficiency 90%

Type-II : SMPS Based Battery Charger:

mbh-i

  • Rectifier Efficiency better than 92%
  • Power Factor better than 0.90%
  • Compact – High Power Density
  • Wide AC input range
  • Output voltage suitable for all types of Batteries
  • Current Stabilization Accuracy less than 0.5%
  • Ripple less than 0.5%
  • Current sharing imbalance for rectifier less than 3%
  • Operate with wide frequency variation.
