Patent number: 9531295Abstract: A resonant power converter includes a DC power source, a positive DC conductor, a negative DC conductor, a phase conductor, and a power converting unit between the DC power source and phase conductor. The power converting unit includes a first switch between the positive DC conductor and phase conductor, a first diode in parallel with the first switch, a second switch between the negative DC conductor and phase conductor, and a second diode in parallel with the second switch. The resonant power converter includes a resonant auxiliary switching circuit between the DC power source and phase conductor. The resonant auxiliary switching circuit includes an inductor in series with a control means, and auxiliary diodes in series with the control means. The inductor is a current discriminating inductor adapted to become saturated by currents flowing through the inductor during normal operation such that the inductance of the inductor is reduced.Type: GrantFiled: July 3, 2013Date of Patent: December 27, 2016Assignee: COMSYS ABInventors: Jonas Persson, Erik Hansson

Patent number: 8976692Abstract: A combination of a phase shifter, a measurement receiver, and an offset estimator enable the d.c. offset in the transmit path of a quadrature transmitter to be distinguished from the d.c. offset in the measurement receiver. The measurement receiver performs a first measurement on the transmit path output with a “normal” phase shift of 0 degrees and 90 degrees for in-phase (I) and quadrature (Q) components, and a second measurement with a “special” phase shift for the I and Q components. In one embodiment, the “special” phase shift for the I and Q components is 180 degrees and 270 degrees, respectively.Type: GrantFiled: January 20, 2011Date of Patent: March 10, 2015Assignee: ST-Ericsson SAInventors: Jonas Persson, Sven Mattisson
