Title: Power supply circuit for heavy ion research equipment
Inventor: HORNEFF HANS
IPC: H02P13/06
Filed: 1984-06-13
Abstract: The supply circuit for an ion source includes an input transformer with a set of e.g eight sections each with a switch so that the primary section can be independently connected to a power supply. Each secondary section is connected to a switch so that all the secondaries can be connected in series to determine the value of the output.  Both sets of switches are connected to an electronic control unit, and the selected output is supplied to a bridge rectifier and a two section cascade circuit, each section connected by an amplifier to an output transformer. The two cascade circuits are in parallel and the positive output terminal is connected to one end of a load connected at the other end by a voltage converter to the negative output connection of the rectifier bridge.  The voltage converter has two outputs for connection to respective nominal/actual value equalisers and a comparator included in the electronic control unit for the switches.  Connected by a series diode at the output of the rectifier bridge is a parallel capacitor.
