IGBT Based Battery Chargers – Precision Control & Dynamic Performance
At Chhabi Electricals, we recognize that modern energy infrastructure demands more than just reliability — it requires precision, speed, and intelligence. Our IGBT-based Battery Chargers are engineered with advanced digital control, delivering fast response, superior efficiency, and stable DC power for the most demanding industrial and utility applications.
>90% efficiency, near-unity PF, low harmonics.
Stable DC even during rapid load variations.
DSP-based control with ±1% voltage accuracy.
Protection from surges, overloads, and thermal stress.
Smaller footprint vs. thyristor chargers.
RS485/Ethernet/Modbus for SCADA/BMS.
Supports multi-mode charging and Li-ion integration
