Abstract : The patent describes a synchronous direct current (dc) power supply which has the power supply input drive synchronized with the pulse repetition frequency (PRF) of the amplifying or load circuit requiring the dc power for operation. This limits the occurrence of ripple components in the power supply output to the spectral positions of the PRF lines, eliminating ripple interference with signal processing in the load. An astable multivibrator is synchronized with the PRF generator output frequency. The multivibrator output is converted to a square wave, filtered, and processed to provide a fully rectified output voltage for coupling to the desired load circuit.
