For the rigorous demand of DC/DC Converter that its over shoot should be within 1%and the problem of discharge to high voltage output in detectors at lunar environment , the output soft start up and multistep boost circuits were designed .The circuit could guarantee the DC/DC Convert-er working reliably in low pressure and was validated in the high-voltage application in lunar survey radar successfully .It may provide support for the design of high-voltage special DC/DC converter in the payload of deep space detector .
