I need it as one of the possbile correction for volt-seconds imbalance in the HF transformer as I can't get my hand of a Current mode PWM controller for the DC-DC section of my inverter, so together with a gap in the centre leg of my HF transformer and usage of MOSFETs as the power switch I...
Hi goldsmith, thanks for the reply.
So, my design calculation and method in the attached doc is okay? also is it okay for me to select and design for the core of the inductor using the selection method for the design of output choke of a DC-DC converter. This is my main problem that I am not to...
Thanks, Please, I have another question, is it possible to find a blocking capacitor that can withstand about 100Amps current to be inserted in series with the primary of my Transfomer for H-Bridge converter configuration.
Also, can I contact your privately if I have other questions?
Hi FvM,
I think that is the heart of my problem and thanks for your replies at least with this I can feel like I am getting closer to understanding how to design inductor.
None of the books I study (Switching power supply Design - Abraham Pressman,Switchmode power supply Handbook - Keith...
Hi , thanks for the reply.
So if I changed my Load current from 1.5A to 1.6A to account for magnetizing current I can still use the design. Or should I changed the design to one using gapped ferrite while using a slightly higher current to account for load current magnetization.
Note: Please...
Hi goldsmith, please check out the design I attached to this reply.
1. I used a constraint of total harmonic distortion of less than 3% of out put voltage and design for inductor that is non-saturate but thermally limited
Design parameters
a. PWM technique is SPWM
b...
Thanks for your reply, the inductance value or calculation is not the issue, the problems is the magnetic design( i mean core selection). Should it be gapped like that of a choke filter design for DC-DC converter filter inductor, or ungapped like the core selected for a transformer or should...
Please, I know how to analytically design and derive values for my low pass filter component at the output an SPWM inverter. But my problem is how to go about selecting the magnetic component to realize my design value. For example let say my calculate inductance value is 2.22mH...
Hello, I am new to EDAboard and magnetic component design and construction. I am trying to construct an SPWM full-bridge DC-AC inverter,
I can design Transformers but I am confused on how to go about the Design and selection of core for the output filter
that will remove the unwanted harmonics...
