Abstract
A power converter utilizes an inverter operating at a frequency near 30 kHz to produce an RF voltage which is divided by a reactive voltage divider, one portion of the divider including a saturable reactor having a control winding which is driven by a negative feedback current from a level sensing circuit connected to the converter output. DC voltage is provided by a bridge rectifier and filter connected across the saturable reactor. The circuit is especially useful for supplying electrical power efficiently to instrumentation on multikilovolt transmission lines where a transformer cascade is used to conductively isolate apparatus operating at the potential of the transmission line from a ground level power source.
