Patent number: 6441652Abstract: A driver circuit for a high frequency switching circuit such as a converter for a gas discharge lamp includes a resonant circuit which transfers energy from the parasitic input capacitance of one or more power switching devices during switching of the latter. The energy transfer prevents dissipation of the capacative energy in the driver circuit which may otherwise destroy one or more components of the driver circuit. The resonant circuit includes a discrete inductor in the driver circuit. Preferably, one or more discrete capacitors are also included within the driver circuit to maintain resonance at a given frequency regardless parasitic capacitance variation.Type: GrantFiled: June 24, 1999Date of Patent: August 27, 2002Assignee: Koninklijke Philips Electroanics N.V.Inventor: Jinrong Qian

Patent number: 5838185Abstract: In a motor controller circuit, an integrated circuit driver drives a plurality of switching transistors which are organized along a top rail and a bottom rail. To reduce the conduction of current through the parasitic diode D.sub.S1 of the integrated circuit, the switching transistors at the bottom rail are provided with individual Kelvin emitter connections, which reduce the parasitic internal inductances, which otherwise produce highly negative voltages when the top rail transistors are turned off. Further, individual traces are provided on the printed circuit board from the COM terminal to the Kelvin emitters. Finally, a small resistance is provided in series with each Kelvin emitter connection which increases the resistance in series with the parasitic diodes and hence reduces the current flowing in the parasitic diodes.Type: GrantFiled: February 3, 1997Date of Patent: November 17, 1998Assignee: International Rectifier CorporationInventors: Ajit Dubhashi, Tyler Fure
