ABSTRACT:
The vital driver utilizes rectification and subsequent synchronized inverting of the rectified power, which is then fed to a transformer. Failed operation, which permits current having a DC component to reach the load transformer, causes an increase in the current which is sensed by a current sensor. The high current can be detected by a fuse. Some embodiments use primary modules having a rectifier section with sufficient power to run a number of secondary units, each powering an individual load. The synchronizing inverter can utilize optically coupled solid state switches.
