What type of controller/control system is suggested here. If we dont synchronize the isolated section what potential problems can I face apart from inductor size , will it hinder the efficiency.
Thanks everobody for your valuable help....
True. What I was thinking was whether dividing it into 10phases would substantially reduce the ripple current ? . I mean not doning the extra effort if say the efficiency only improves marginally after 4phases... This thing I am not sure .
Sorry for the confusion, I attach a block diagram for clarification below;
What I mean is the each interleaved section is isolated too. So when the boost stage gets interleaving signals , its asociated HF isolation stage indirectly works in acordance. Is this ok, or we need multiple sections .

Thanks for the clarification, here can we assume that the isolated section of each phase will work in accordance with it indirectly(Dc o/p) . Do you say nominally the the duticucle should be at 67 or 87 percent.
Its two stage BOOST ----> Isolation. I think you misunderstood me . I mean using only 2 PWM channels for H bridge and the rest high side Fets to remain in on/off state (Pls find below image).

Please accept my apologies , I couldnt reply earlier .....
Yes separate transformer, and its excited with a full bridge (4 MOSFETS). I am exploring this , so I have not yet com up with schematics.
If we drive the MOSFET channels , is it necessary to complement the PWM on alternate channels...
Thanks for the reply, please advice me what is the case which require overlappin?
I also need to know for sinus signals sequencing in 'N' number of interleaved channels. Do we start and stop the cycles in each channel, every 36degrees added intervals for each channel one after another. OR we...
Dear Members;
I need to design a DC-DC isolated converter the Dc bus voltage is 50VDC and I want to interleave the current (500Amps) to 10 channels . Then it should be 360/N channels , my question is can we select a longer timeperiod say 720degrees/N . It might sound ridculous.
I also need...
RS485-network
For a standard Max485 how much maximum current
one transceiver consumes from the board is it 1mA? or 140mA? maximum.
The datasheet points to ;

In this particular software , when the mouse is pointed over an object we get a 'Tool Tip Text' , can anyone help me how to disable this funny item ?
Thanks

Thanks for the exact reply , could you please help me with the bending of this microstrip (right angle is said not to be a good practice), how is the curvature calculated , though my frequency is too low 433MHz.

Hi,
Attach is the placement for 1206 Resistors for ateunaton . Please review if its OK to place this way . OR should I orient the Resistors right angled to the modules Antenna o/p port? will use a microstrip to feed till antenna .
Thanks
Ts
