<p>A power supply for laser systems is configured with a DC power source having an output source voltage, an energy accumulator operatively connected to the output of the DC power source, and a pump. Coupled between the accumulator and source is a first DC to DC stage with at least one switched-mode power converter which is operative to charge the accumulator with voltage. The charged voltage may be same or different from the source voltage. The power supply further includes a second DC to DC stage with at least one switched-mode power converter coupled between the accumulator and pump and operative to discharge accumulator to the same or different output voltage. The DC to DC converters are configured so that current pulses at the input of the pump each have a peak value greater than the power source current.</p> |
