Hi All,
i have uploaded a zip-file named DAB500_zip.7z, placed in the temp.-folder.
?
You will find the following files:
- Simulation file for the 500W DAB-Converter with same specifications as previously discussed.
- one for static Load operation, to mdeasure the Efficiency, which reached realistic 93% to 95%
- one for pulsed Load operation from 0,83A to 3,33A with di/dt of 2,5Amps/usec.
- Also attached are lib-files, such as for the UC3875-controller, the current transformer and a Compensator?
with isolated feedback loop. (Replacement for optocoupler).
?
Of course, the UC3875 phase shift controller is old-fashioned, but enough to demonstrate the functionality of the DAB-converter.
If anyone has a modern, up-to-date controller for LTspice, kindly give me an input.?
?
With some minor modifications, the circuit may be used for bidirectional power flow.
