of energy are being processed in accordance with this aspect of the invention conductors which connect circuit components comprise copper tubes or tubes consisting of any highly conductive material a coolant such as water is actively circulated by a forced flow or pressure differential or other convenient means through the conductive tubes in order to effectively dissipate heat developed from the power supply circuitry at 150 kw output water circulates at about 5 gpm gallons per minute according to a preferred embodiment in addition each series resonant inverter module includes a built in manifold which circulates coolant such as water to the circuit elements the coolant manifold is preferably placed on top of the transformer the manifold structure preferably incorporates a coolant filled member or so called 34 cold finger 34 disposed around the transformer core for effective dissipation of heat the manifold also actively circulates the coolant through the conductive tubing which joins the various circuit elements the coolant manifold is preferably also comprised of a malleable conductive material such as copper in order to fit conformably over the core of the transformer referring to fig5 both the primary and secondary windings of the transformer 500 comprise coolant filled conductive tubes 510 a coolant such as water is forcibly circulated through the tubular windings in order to provide extremely efficient cooling of the transformer the diodes 504 505 506 and 507 in the series resonant inverter module also carry approximately 50 kw at 700 volts the diodes 504 505 506 and 507 are cooled by means of the water circulating through conductive tubing which also connects the diodes with other circuit elements the.
