Abstract

Control means for a power-converter WR enables automatic testing of the operational readiness of the converter for parallel operation with other converters (not shown) at a common load rail S. A control unit 1 controls and monitors operation of the converter, a control unit 2 regulates the output power via unit 1, and a control unit 3 tests the readiness for parallel operation. Following preliminary testing of the control, monitoring and power regulating functions of units 1, 2, signals on lines 101, 102 cause unit 3 to effect the parallel operation readiness test. Unit 3 causes units 1 and 2 to first control converter WR to give a higher than nominal output and this is checked by a voltage monitor SpW resulting in an acknowledge signal on line 106. Units 1 and 2 are then caused to operate converter WR at a lower than nominal voltage, resulting in an acknowledge signal on line 107. If both signals 106, 107 are obtained, a contact K3 is closed to connect converter WR to line S. Absence of either or both of signals 106, 107 indicates unreadiness for connection and the converter is de-energised via AND gate 3/5 and line 108 when a timer 3/1 of unit 3 times out.
