Abstract: A communication system for use in a switching module includes a low-side control block coupled to control switching of a low-side switch of the switching module. The low-side control block is further coupled to be referenced with a low-side reference system ground. A high-side control block is coupled to control switching of a high-side switch of the switching module. The high-side control block is further coupled to be referenced with a floating node of the switching module. During steady state operation, the low-side control block is coupled to send signals during each switching cycle to the high-side control block to turn the high-side switch on and off. A status update is communicated from the high-side control block to the low-side control block through a first single-wire communication link.

Abstract: An inductive rotating power transfer circuit, preferably for transferring electrical power from the stationary part to the rotating part of a CT scanner comprises an inductive power transformer having a stationary primary side and a rotating secondary side. The secondary side is connected via a rectifier to a filtering capacitor, delivering electrical power to a load. One of the output pins of the filtering capacitor is connected to a secondary ground at the rotating part which is further connected to a stationary protective ground via a galvanic slip ring. In the case of a short circuit between a secondary transformer winding and the secondary ground, the secondary winding is partially short-circuited by one of the rectifier diodes. This causes an asymmetric current load at the primary side and a current flowing through the slip ring. Both currents may be used to detect a failure of the secondary winding.
