1. In a liquid cooled switching regulator power supply having at least one power module, said module having a pair of reactors, each reactor having a primary winding and a secondary winding, a pair of current switches for controlling current flow through the primary windings of the reactors, current rectifying means having an anode and a cathode connected in series with the secondary winding of the reactor to rectify current flow through said secondary winding, a first and a second chill plate, a liquid cooled heat exchanger for cooling the chill plates, means for fastening the chill plates and heat exchanger together so that the heat exchanger can cool the chill plates, the improvements comprising:

  • means for electrically insulating the chill plates from each other;

    the reactors, current switches and current rectifying means of the power module being mounted on the first chill plate;

    the anodes of the current rectifying means of the power module being connected to the first chill plate and the cathodes of the current rectifying means being connected to the second chill plate through the secondary winding of the reactor, whereby the first chill plate is the negative power bus and the second chill plate is the positive power bus of the power supply.
