Abstract
We disclose herein a power coupler for connecting AC or DC electrical circuits having different voltages, current or impedance levels. The power coupler comprise a first switching device; a second switching device coupled with the first switching device; a power transformer comprising a first core winding and a second core winding; a first capacitance coupled between the terminals of the first core winding; a second capacitance coupled between the terminals of the second core winding; and a third capacitance coupled between the first and second cores windings. The power transformer is coupled with the first and second switching devices. The power coupler is configured to reduce switching power loss using an adiabatic technique and by selecting appropriate switching time of the switching devices.
