Abstract
Disclosed herein is a dual-active bridge converter and methods of operating the same. The dual-active bridge converter can include a transformer, a DC-AC converter, an AC-DC converter, and/or a control device. The DC-AC converter can be coupled to a first DC bus and a primary side of the transformer. The AC-DC converter can be coupled to a secondary side of the transformer and a second DC bus. The control device can send a first PWM signal to the DC-AC converter and a second PWM signal to the AC-DC converter. The first and second PWM signals can initiate the output voltage at zero, add jump edges at odd-numbered current harmonics, or make a phase of the input voltage trail a phase of the output voltage of the DC-AC converter. The control device can adjust the PWM signals for transformer current regulation or pulse overlap control.
