two half bridges, from fully overlapping to fully our of phase

Prodigy 40 points

Hello E2E,

"In our LLC converter during phase shift mode, we are operating a full bridge with 4 FETS. The Fets are setup so they are Complementary in a half bridge pair, with deadband. We can then vary the phase offset at a fixed frequency between these two half bridges, from fully overlapping to fully our of phase.

So my question is, we have PWM1 sending a SYNC out pulse on ZERO to PWM2, and PWM2 then uses the TBPHS register to configure the phase relationship. It seems to work, but I had a feeling someone suggested you couldn’t resync PWMs every cycle as there was an issue. I do not observe any problem, but wanted to make sure with you first before we went down a rabbit hole!!"
