摘要： 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.

摘要： 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.

摘要： The present invention relates to a closed loop class-D amplifier. The amplifier comprises a feedback arrangement with a low frequency path and a high frequency path. The high frequency path is used to obtain a self-oscillating condition in the amplifier and may contain passive components. The low frequency path comprises a low pass filter and a waveform correction circuit that reduces the amplifier distortion. Since the waveform correction circuit is applied in a low frequency path, the waveform correction unit may be realized using e.g. operational amplifiers that need not be rated for high frequencies. This allows a class-D amplifier to be realized with improved distortion and at a low cost.
摘要翻译：本发明涉及闭环D类放大器。放大器包括具有低频路径和高频路径的反馈装置。高频路径用于在放大器中获得自振荡状态，并且可以包含无源部件。低频路径包括降低放大器失真的低通滤波器和波形校正电路。由于波形校正电路被应用在低频路径中，所以可以使用例如波形校正单元来实现波形校正单元。运算放大器不需要对高频进行额定。这样可以实现具有改进的失真和低成本的D类放大器。

摘要： 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.

摘要： A voltage regulating circuit comprising a rectifier (2) for receiving an AC voltage (V mains ) and for generating a rectified AC voltage (v rec ), and a capacitor (3) connected in parallel with said rectified AC voltage for providing a DC voltage (V DC ) 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 (v rec ) so that said DC voltage (V DC ) 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.

摘要： 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.
