An opportunity to license this technology
Herbert is very active inventor in the area of power conversion.
His most famous invention is the matrix transformer which he licensed in
the 1980s. Since that time he has authored many more patents in
the power electronics technology.
September 15, 2005 - Edward
Herbert was granted U. S. Patent No. 7,098,638 on August 29, 2006. This
true digital power conversion topology builds on the switched-current
power converter technology and extends its application to the processor
The parasitic impedance of the interposer limits the dynamic response of
an external power supply. Using the totem-pole power converter for
processors, the impedance of the interposer is no longer a problem; it
becomes part of the solution.
Mr. Herbert points out, "The greatest waste of power in a processor
is the loss due to the leakage current when the processor is idle. By
reducing the core voltage to zero, all of that power is saved. This was
not possible until now, as the processor has to be "ready,"
and it took too long to restore the voltage. The switched-current power
converter has very fast dynamic response." It can transition from
no load to full load in less than a microsecond. The recently-issued
patent shows how to use "passive ballasting" to divide a
constant current into a large number of smaller constant currents. The
ballasting is very small parallel inductors, and the self-inductance of
parallel circuit board traces is sufficient for most applications.
Using the switched current technology with switched charge, the voltage
can go from 0 volts, 0 amps to any VID, any load current in less than a
microsecond, and it can go from any VID, any load current to 0 volts, 0
amps just as fast.
March 2006 - The Switched Current
Power Converter technology is expanded to include semiconductor device
in the form of a simple power integrated circuit. See the
"Simple IC" write up below.
January 31, 2006 - The Switched Current
Power Converter technology to be presented at the Conference on
Enterprise Servers and Data Centers: Opportunities for Energy Savings.
November 2005 - Dr. Scott Strand of IBM started introducing this
technology at his next monthly e-supplier meeting with the message,
"We have taken a look at this technology and, from a theoretical
perspective, we see there is some potential advantages that could be
realized from this technology. We would like you to take a look at it,
have some discussions, and see where you would like to have this
Herbert's latest innovations are two advance performance power converter
Switched Current Power Converter (SCPC) that provides very high di/dt
power source performance, eliminating all of the bulk capacitors
presently under and around the microprocessor.
Switched Charge Circuit (SCC) that provides very high dv/dt made
necessary with the advent of Intel's "Demand Based Switching.
