Patent number: 9917515Abstract: The extended commutation cell (ECC) is a four-port, four-switch cell that allows for bidirectional energy transport in two orthogonal directions throughout the cell. By cascading multiple cells, a multilevel converter can be constructed with a high number of levels. The voltage across each cell capacitor can be adjusted independently of the load, resulting in high flexibility in output levels. Improved fault tolerance is also provided.Type: GrantFiled: November 6, 2015Date of Patent: March 13, 2018Assignee: Technische Universiteit EindhovenInventors: Erik Lemmen, Jorge Luiz Duarte

Publication number: 20080212340Abstract: For converting a first DC voltage to a second DC voltage, a first bridge circuit comprised in a power converter is controlled to convert the first DC voltage to a first AC voltage. The first AC voltage is transformed to a second and possibly further AC voltage. The second and each possibly further AC voltage is converted to a DC voltage by respective bridge circuits. To increase efficiency of the power converter switches of the power converter are controlled to operate in soft switching. Thereto a duty cycle of each AC voltage is controlled. In an embodiment, a half-cycle voltage-time integral of each AC voltage is controlled to be substantially equal.Type: ApplicationFiled: June 2, 2006Publication date: September 4, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Haimin Tao, Andrew Kotsopoulos, Jorge Luiz Duarte, Machiel Antonius Martinus Hendrix

Publication number: 20080123379Abstract: A voltage regulating circuit comprising a rectifier (2) for receiving an AC voltage (Vmains) and for generating a rectified AC voltage (vrec), and a capacitor (3) connected in parallel with said rectified AC voltage for providing a DC voltage (VDC) over a load (5), characterized by a unidirectional current switch (4) provided between the rectifier (2) and the capacitor (3), and a control block (6) arranged to activate the switch (4) at selected instances (7) during negative slopes of the rectified AC voltage (vrec) so that said DC voltage (VDC) does not exceed a predetermined voltage limit. By controlling the voltage provided by the rectified mains, the DC voltage can be regulated to any preset value (lower than the AC mains peak value). The inventive voltage stabilizer will guarantee a desired constant DC load voltage value for different mains peak input voltages and under wide range of load variations. Thereby a converter driven by this voltage can be more optimized or even be unregulated.Type: ApplicationFiled: April 6, 2005Publication date: May 29, 2008Applicant: KONINKLIJKE PHILIPS ELECTRONICS, N.V.Inventors: Pieter Jan Mark Smidt, Jorge Luiz Duarte

Patent number: 7031176Abstract: In a system for the conversion between DC power and AC power, including a buffercapacitor and a controllable converting arrangement, said conversion is controlled by a power control quantity that in turn depends on a first component assuring a balance between DC power and AC power and a second component indicating a change in energy stored in the buffer capacitor on a predetermined sampling time instant in the cycle of the voltage ripple on the buffer capacitor.Type: GrantFiled: June 25, 2003Date of Patent: April 18, 2006Assignee: Koninklijke Philips Electronics N.V.Inventors: Andrew Kotsopoulos, Machiel Antonius Martinus Hendrix, Jorge Luiz Duarte

Patent number: 7015754Abstract: An amplification device is disclosed providing a way of integrating a switch mode power supply and a class D amplifier (switch mode amplifier). This results in the usage of basically one magnetic component (1), one major energy storage element (4) and switches (20, 30) that are controlled in such a way that both the power supply function and the amplification function are achieved. In this way a cheap, small and highly efficient current configuration is achieved. This amplification device is especially useful in audio products.Type: GrantFiled: November 20, 2002Date of Patent: March 21, 2006Assignee: Koninklijke Philips Electronics N.V.Inventors: Pieter Jan Mark Smidt, Jorge Luiz Duarte, Rudi Jonkman

Patent number: 6498456Abstract: To improve the performance of an inductive coupling system, the magnetic coupling between the primary (4) and secondary (8) windings is increased by adding auxiliary windings (26,28) on the primary (2) and/or secondary (6) yokes of the assembly near the air gap (18) between the yokes. Capacitors (30,32) are connected to the auxiliary windings (26, 28) which, together with the inductance of the auxiliary windings, resonate at the operating frequency of the primary AC voltage (Vp). The effect is an improved magnetic coupling between the primary and secondary windings (4, 8) without increasing the size of the magnetic assembly.Type: GrantFiled: February 27, 2002Date of Patent: December 24, 2002Assignee: Koninklijke Philips Electronics N.VInventors: Wilhelmus Gerardus Maria Ettes, Jorge Luiz Duarte, Johannes Lambertus Franciscus Van Der Veen
