TIDA-01606: PFC topology

Part Number: TIDA-01606

Working on TIDA-01606 and I need to know the principle topology used in the design 

Is it Boost or Buck ?

thanks

    Hi,

    when TIDA 01606 is attached to the grid the DC voltage can be increased with respect to the grid.

    This means that in PFC operation TIDA 01606 works as a boost converter.

    Just to give you an example:

    • when the T-type converter is off the DC bus voltage will be around sqrt(2)*(Vline to line)= sqrt(2)*380 = 540 V
    • when you turn on the PFC the voltage of the DC bus will rise and you will be able to control up to a maximum value that is given by the semiconductor technology (e.g 800 V)

    Best regards
