I am working on a dual active bridges (4 mosfets instead of 4 diodes) by sw itching directions using either: 555, CPLD, FPGA or micro, depending on tim ing complexity. In the simplest case, just a 555 switching primary and sec ondary at the same time. In more complicated case, a micro switching with turn-on delay T1, turn-on time T2, turn-off delay T3 and frequency F1.
What are the estimated efficiencies with:
- T1, T3 = 0
- T1, T3 0
For instance, 20 degrees T1 to ramp up magnetic field on the primary, 140 d egrees to drive secondary and 20 degrees to ramp down.
What would be the best F1 for driving a microwave transformer at around 12V ? Perhaps outside audio range to avoid humming.

OT: Cashmunism, nobody does it better
For an unnamed country with 1.4 billion people. When 40% of the population makes less than US$150 a month, one of the 2nd t ier leader is worth US$500M. Can't name the specific country, or this could be censored or be attacked f rom down under by proxy (or Bill).
- Capitalism: money is fair game
- Fascism: only the leaders are entitled to the money
- Communism: people must suffer for the leader's worth
- Cashmunism: only cash matter, nothing but the cash

OT2: Fees are better after BK.
The Hertz lawyers decided to offer more stocks to exit BK at around 1/3 pri ce pre-BK. Why didn't they offer it before BK? Well, the company might ge t more money, but the lawyers would not get as much as in BK.
Capitalism at it's best (or worst).
