  • Where Are Industrial Frequency Battery Chargers Used in Metro Systems?

    Where Are Industrial Frequency Battery Chargers Used in Metro Systems?

    Apr , 16 2026
    In a metro system, many critical devices operate behind the scenes. One of them is the DC battery charger. It charges backup batteries during normal operation and supplies DC power when the grid fails. Although high-frequency chargers are smaller and more efficient, industrial frequency (SCR-based) chargers are still widely used in metro systems. The reason is simple: rail infrastructure prioritiz...

    Why Industrial Frequency Chargers Are Still Used After 30 Years

    Mar , 20 2026
    Even as power electronics evolve rapidly, one “old-timer” has remained essential in industrial applications—power plants, substations, and rail systems: the industrial frequency (IF) charger.   High-frequency switch-mode power supplies are efficient, compact, and cost-effective. So why do IF chargers, seemingly “heavy and outdated,” persist? The answer: in critic...
