Novelty Zero Current Detection Sensor for MHz frequency range
Year: 2025
Type: article
Abstract: For the purposes of the EU co-funded project DEEP PPU, consortium partner FRAZA has developed an advanced Zero Current Detection Sensor (ZCD sensor) having an extremely low latency, volume and losses. The most suitable yet simple concept of zero current detection utilizes a small transformer driven into saturation. This concept hides significant potential of achieving very low losses, a good noise immunity, high accuracy and fast responsiveness. The concept operates by detecting the moment of the magnetic core falling out of the saturation at the moment of the current changing the polarity. The change in flux of the magnetic core induces voltage in a detection coil which is then reflected in a form of a voltage pulse.
