Hi,

In TIDA-00779 3.5KW PDC design, why two boost diodes(D1, D3) are used? also how to calculate D2 and L4? plz reply

    Hi Desai,

    Because the maximum current flow from the diode is very big at low line input, we used two diodes in parallel to increase the current capability, for L4 you can short it if no EMI concern, for D2, you can calculate it by the value of bus capacitor, which is designed for inrush current at starting.
