Extending SMPS technology to kilowatts represents an improvement in reducing the volume and weight of DC supplies. Output power up to 10 kW is available in any combination of voltage and current, with an upper voltage limit of 600V and a current limit of 1000A. Higher power outputs are feasible with series/parallel combinations. For high-power output, a 3-phase input is recommended. Typical applications include high-current battery chargers, DC UPS systems for critical loads, and electroplating supplies.
