Title: Series resonant dc-dc converter
Inventor: STANLEY GERALD R
IPC: H01F27/42
Filed: 2006-09-18
Abstract: A series resonant DC-DC converter 300 for powering an audio amplifier as a load may include a power input stage 310, a switching stage 320, which may be a half-bridge or full-bridge switching stage, a series resonant stage 330, a transformer stage 350 and a power output stage 370. The series resonant DC-DC converter 300 further may include a clamping stage 340 and a leakage inductance canceling stage 334. The clamping stage 340 may operate to clamp an excess voltage generated at least by a leakage inductance Ls and a parasitic capacitance Cp. The leakage inductance canceling stage 334 may operate to generate a voltage drop corresponding to a voltage drop generated by the leakage inductance Ls. The generated voltage drop may be subject to clamping. The clamping stage 340 may operate under all load conditions without any influence of the leakage inductance Ls. As a result, the series resonant converter 300 may achieve improved load regulation.

Title: Switching power converter employing pulse frequency modulation control
Inventor: RIBEIRO MILTON D
IPC: H02M3/158
Filed: 2006-01-05
Abstract: A method for controlling a switching power converter provides an efficient algorithm for controlling the output voltage across loads that are relatively light with small transients. When the output voltage is at or below a predetermined first magnitude, a determination is made of the charge required for one or more pulses to increase the output voltage to a predetermined second magnitude which is greater than a target output voltage. Corrective action is taken to raise the output voltage to the second magnitude and the system takes no further corrective action until output voltage is determined to be at or below the first magnitude. The method is useful with synchronous or non-synchronous power converters of buck, boost, buck/boost or other topologies. The method further provides a simple means for determining the amount of charge removed from a battery.
