TIDA-01604: Use same architecture with a 3-phase AC source

Intellectual 300 points
Part Number: TIDA-01604

Hi,

i'm wondering if the architecture illustrated in the TIDA-01604 document is usable with a three-phase AC source instead of a single-phase AC source as presented in the TIDA-01604.

My concern are:

  • Can we use the same architecture? (e.g. same numbers of transistors, connected at same way)
  • Is the PWM activation logic the same as the one presented in the document?

Thanks very much

    Hi Nicola,

    TIDA-01604 itself can only be operated in single AC input architecture. It needs modification in order to support 3 phase: the low frequency MOSFETs needs to be increased to 3 half bridges to support each phase respectively. TIDA-01604 has only the single phase. The PWM scheme needs to be modified to adapt to the three phase architecture as well.

    Hi Nicola,

    We would also like to point to the following two designs as they will both be able to handle 3 phase AC/DC conversion uni-directional for the first one and bi-directional for the second one.
