In the DAB experiment, as shown in Figure 2: red (hand-painted) is the theoretical waveform of the secondary side of the high-frequency transformer in the DAB, yellow is the measured waveform of the secondary side of the transformer, and pink is the primary side waveform of the transformer. There is a phase shift on the two sides of the transformer, which is reflected in the red and pink patterns. The problem is that the yellow and red waveforms obtained by the experiment are inconsistent.
Preliminary analysis: The size of the difference happens to be the size of the phase shift, as shown below.
Have you encountered such a problem? How to solve it?
The simplest single phase shift control is adopted, the two side has a phase shift, the tubes on the same side are turned on at the same time, and the same bridge arm is complementarily turned on.
