摘要： Die Erfindung betrifft ein Verfahren zur Minimierung der ersten Harmonischen des Quellstroms bei Versorgung von mehreren Konverterstufen aus einer Quelle. Die Amplitude und die Phasenlage der Grundschwingung der einzelnen Konverter werden so zu einem Zeigerdiagramm zusammengefügt, dass ein geschlossenes Zeigerdiagramm entsteht oder der resultierende Zeiger minimal wird und daraus wird die erforderliche Phasenverschiebung der Einschaltzeitpunkte der einzelnen mit gleicher Schaltfrequenz betriebenen Konverter bestimmt. Dadurch werden definierte Belastungsverhältnisse der Quelle geschaffen und akustische und elektrische Schwebungen verhindert. Minimierung der Grundschwingungsamplitude verringert den (störenden) Effektivwert der Harmonischen des Quellenstroms und erleichtert die Filterung, da nun nur mehr die höheren Harmonischen durch Shuntkondensatoren überbrückt werden müssen.

摘要： The invention concerns a driver device for electrically driving a motor for sliding a panel of an electric window or sliding roof of a vehicle. The driver device is provided with a supply circuit for generating a pulse-width modulated supply voltage for driving the motor with a variable speed. The driver device is further provided with a rectifier circuit which is connected on one side with the supply circuit for obtaining, on the basis of the pulse-width modulated supply voltage, a direct voltage whose magnitude is dependent on the pulse width of the supply voltage, and which is connected on the other side with the motor for driving the motor with the direct voltage, the speed of the motor being dependent on the magnitude of the direct voltage.

摘要： The invention concerns a powering unit comprising at least one transformer (TR1), at least one full bridge circuit via which a primary winding of the transformer (TR1) is connected to a direct current voltage input (UE), a secondary winding for triggering an output circuit with an output direct current voltage (UA) via a bridge-type rectifier circuit as well as an output choke coil (L2) and an output capacitor (C2), and a discharge circuit consisting of a diode (D5), of a capacitor (C4) and of a resistor (R1) for reducing the secondary-side peak voltages. The invention is characterized in that another secondary winding, another bridge-type rectifier circuit and another discharge circuit are operable to trigger the output circuit with part of the output direct current voltage (UA) via the output choke coil (L2) and the output capacitor (C2). Thus, there are fewer losses in the resistors (R1, R2) and the performance is enhanced.

摘要： In a power supply apparatus including a plurality of power supply circuits, each of the power supply circuits has a piezoelectric transformer, a rectification element which rectifies and smoothes a voltage output from the piezoelectric transformer in accordance with a load and outputs the voltage, a voltage-controlled oscillator which controls the frequency of an output signal in accordance with an input control signal, and a power supply voltage supply element which is driven by a signal output from the voltage-controlled oscillator and supplies a power supply voltage to the piezoelectric transformer. One power supply circuit includes a resonance frequency change unit which is connected to the output side of the piezoelectric transformer. The resonance frequency change unit drives the piezoelectric transformer of the power supply circuit at a driving frequency which is different from the driving frequency of the piezoelectric transformer in another power supply circuit by shifting the peak of the resonance frequency.

摘要： A method to avoid saturation of the magnetic core (M) of an inductor coil (L) includes the steps of providing a bypass circuit (BP) across said inductor coil (L) for bypassing a DC current to said coil. Such a bypass circuit includes a regulating circuit (RE) to control the amount of DC current which is bypassed, and may further include an active gyrator (G) for the bypass of the DC current. This invention is applicable to one single coil (L) or to any circuit including a series connection of coils. In the latter case one or more bypass circuits may be provided across either one or more series connected coils.

摘要： An improved DC-DC converter with reduced input current ripples. The converter includes a transformer, a switch, and a capacitor. The switch turns on and off alternately to store the energy in the transformer. The capacitor is connected in series with a rectifier and a secondary winding of the transformer across an input DC voltage so as to be charged by the energy released from the secondary winding through the DC power source. Accordingly, the circuit sees an input current which continues flowing through the DC power source even the switching element is turned off.

摘要： A wave shaping circuit is provided having an input node, an output node and a ground node. A first circuit is connected between the input and ground nodes, and a second circuit is connected between the output and ground nodes. The circuits operate so that in a first mode, such as at low RMS line voltage, a V1 signal passes through the wave shaping circuit without being modified as to shape. In a second mode, such as at high RMS line voltage, the line voltage signals are modified to provide flattening of the peak of a waveform provided at the output node.
