Other Parts Discussed in Thread: TIDA-01604

Why in OBC-DC/DC, the DC/DC is fixed about several kilowatts like 1kW~3kW, what is the design consideration and can it be increased?

    Hello Zirui,

    the power demand is based on customer request; myself got OBC requests up to 22kW.
    If you want to look at our homepage TIDA-01604 (totem pole bridgeless PFC)
    and PMP2199 (CLLLC resonant dual active bridge) are forming a 6.6kW bidirectional
    onboard charger to supply EV.

    This design will be showed and discussed by a design review during our web based
    Power Supply Design Seminar 2020, topic #5 - feel free to register.

    So to answer your question - output power depends on application and YES, power could be
    increased >3kW.

    Best regards, Bernd
