<p>The present solution relates operation of a power conversion device (200, 500). A first gate (205, 505) is operated (901 ) to provide a voltage pulse (309,609) travelling from an input (201,501 ) to a wave propagation medium (105) through the first gate (205,505). The voltage pulse has duration (307,607) less than the propagation time through the medium (105) to one end of the medium (105) and back to the input (201,501 ). The pulse generates a reflected wave. The first gate (205,505) is operated (902) periodically providing a voltage pulse in synchronization with the reflected wave to accumulate the reflected wave travelling in the medium (105), performing the accumulation through an accumulation interval (303,603). A second gate (207,507) is operated (903) periodically to provide a discharge pulse (312,612) in synchronization with the reflected wave to discharge the wave travelling in the medium (105), performing the discharge through a discharge interval (310,610).</p> |
