Abstract
A resonant power converter. An embodiment with a fullbridge converter is disclosed, controlled with feedback or feedforward technique. Switching schemes are either based on a sort of look up table or on measurement of current or voltage. Dead time may be adjusted. Timing may be such, that in the respective diagonal pairs of the converter, one switch is switched on for a different time (different pulse width) than the other. Use in a relative high power environment for about 20 KW in e.g. an X-Ray or Computer Tompgrapy System.
