Methods and devices for power conversion. High frequency electromagnetic waves traveling in coupled transmission lines and their reflective properties are used to perform the power conversion. The use of high frequency operation allows for physically small transmission lines. The high operating frequencies also allow for small filter capacitors at the outputs of the power converter and hence allowing for fast response times in load changes or fast signal changes in case of a gate driver. The transmission lines can be implemented on the printed circuit board, laminate or even on chip. In case of a step up converter the switching elements are not subjected to the higher output voltage levels of the power converter and can therefore be implemented in a lower voltage process technology. Further, embodiments with and without galvanic isolation are described and physical embodiments to reduce undesired electromagnetic emissions are disclosed. |
