Abstract
The present invention relates to a solution for electrical power conversion using a first gate (202, 302) for starting an electrical wave in a wave propagating medium (205, 306) acting as a transmission delay where an electrical wave propagates and due to reflections in the propagating medium a resulting wave builds up and is transferred to an output for delivering a power amplifier, DC/DC converter or similar function and the output is controlled using a second gate (204, 304).
Claims15
An electrical power conversion device, comprising
- at least one electrical source input;
- at least two electrical gates;
- at least one electrical wave propagation medium;
- and
- at least one electrical output connectable to a receiving output load;
- wherein the electrical source is configured to apply a voltage to the electrical wave propagation medium through a first gate for a time duration 2td exceeding the wave propagation time through the electrical wave propagation medium to one end of the electrical wave propagation medium and back to the electrical source, accumulating an electrical wave travelling in the electrical wave propagation medium, wherein a second gate is configured to control the resulting accumulated electrical wave at the electrical output, and wherein the first and second gates are in a conducting position substantially separated from each other in time.
A method for converting electrical power using an electrical wave propagation medium, comprising the steps of:
- providing an electrical source to the electrical wave propagation medium using a first gate;
- providing the electrical source during a time exceeding the wave propagation time of the resulting electrical wave travelling in the electrical wave propagation medium to one end and back to the electrical source;
- controlling the resulting electrical wave at an electrical output using a second gate;
- wherein the first and second gates are in an on position substantially separated from each other in time.
