Hello all.
The H-bridges are working fine. I employed phase shift modulation for voltage regulation. However the transformer output voltage shows lots of ringing and distorted waveform. The attached picture is the two LLC resonant tanks. The two transformers share a common core.
The waveforms...
Thanks alot FvM and Easy Peasy.
I troubleshooted the problem. I had been using optocoupler based gate drive with variable gate resistor. The problem existed with the gate driver. Need to vary the gate resistor to get the square wave from H bridge.
Moreover, the ringing issue is supressed by...
Thanks for the reply.
Sorry, Can't show the topology schematic here.It's confidential at this stage.
The offset occurs in both H-bridge output as can be seen from blue and pink waveforms.
Can the mismatch of 10uH in magnetizing inductance result in such offset?
Hello all, I am designing a bidirectional DC DC converter comprising of two resonant tank. My topology is like two H bridge giving two square wave output to two LLC resonant tanks. I am employing PFM to maintain constant output voltage.
I have designed single core dual primary dual secondary HF...
