2 / 17 page  2 www.irf.com ML1000605D (100V Input, Dual Output) Circuit Description An under-voltage protection circuit prohibits the converter from operating when the line voltage is too low for safe operation. In case of an under voltage event the converter will not start when the input voltage returns to its nominal level before an Off-command followed by an On-command has been issued. The isolated On/Off telecommand is made with a latching relay and is intended for use with a 26V pulse command. A status telemetry derived from a spare set of contacts in the relay is used for status telemetry. Design Methodology The ML-Series is developed using a proven conservative design methodology, which includes selecting radiation tolerant, and established reliability components and full derating to the requirements of EEE-INST-002 and ECSS-ST-11A. The ML-Series converters utilize two-stage regulation with a flyback topology with a switching frequency of 140kHz for primary regulation and linear post regulation for each of the outputs. The Output power is limited under any load fault condition to approximately 120% of rated output. An overload condition on the positive output causes the converter output to behave like a constant current source with the output voltage dropping below nominal. An overload condition at the negative output causes the positive output to shut-down in order to protect RF-transistors in the load. The converter will resume normal operation when the load current is reduced below the current limit point. For further information please refer to the ML-Series generic description available at www.irf.com. |
