摘要： A switched mode power supply comprises a switched mode converter (12) and a controller for controlling the switched mode converter, wherein the switched mode converter is provided for converting an input voltage (Vin) to an output voltage (Vout) and includes, on a primary side, a primary winding (X1) and a controllable switch based circuitry (31) connecting the input voltage over the primary winding; and, on a secondary side, a secondary winding (X2) coupled to the primary winding, and a capacitive element (C) connected over the secondary winding, wherein the output voltage is obtained as the voltage over the capacitive element. The primary winding comprises a first winding portion (np1) and at least one further winding portion (np2); and the switch based circuitry comprises controllable switches (Q11, Q41, Q12, Q42, Q21, Q31) capable of switching between a first operation state wherein the input voltage is connected only over the first winding portion and at least a second operation state wherein the input voltage is connected over the first and the at least one further winding portions, thereby enabling switching between two different transformer ratios (n1, n2).

摘要： A control circuit for a switched mode power supply and a related method are provided for controlling switching elements in a power train of a switched mode power supply. The control circuit comprises a mode controller to monitor the output current to determine whether the output current exceeds a current threshold. The mode controller controls the switching controller to generate the switch control signals. When the current exceeds the current threshold, the power train operates in a continuous conduction mode, and upon determining that the output current has fallen to or below the current threshold, the operation of the power train is changed from the continuous conduction mode to a pulse skipping mode. The pulse skipping mode is entered from the continuous conduction mode and involves determining the amount of energy stored in a secondary circuit of the power train.

摘要： A wireless communication device can provide an indication that its registration in a circuit-switched domain of a network is intended only for a short message service that is included in or accompanies a registration request, such as a combined registration for both the CS domain and a packet-switched (PS) domain. The device can also change a conventional order of its domain registrations, e.g., by performing a PS-domain registration before a CS-domain registration, when it will send SMS messages over the PS domain. The device can indicate its intention to use or support for SMS over the PS domain and/or be informed about network support for SMS over the PS domain before the UE attempts a network registration.

摘要： An intermediate bus architecture power supply system including an output voltage feedback-regulated, isolated first stage switching voltage converter (SVC) such as an intermediate bus converter, connected via an intermediate voltage bus (IVB) to at least one second stage DC-to-DC voltage converter. The first stage SVC is configured to adjust its switching duty cycle to compensate for voltage fluctuations on the IVB. The voltage regulation mechanism of the first stage SVC may thus suppress oscillations in the IVB voltage which originate from the first stage SVC's input or from fluctuations in the system's load current, and consequently reduce electromagnetic interference as well as the amplitude of voltage and current fluctuations on the IVB.

摘要： A multi-layered printed circuit board, PCB, includes first windings for a first side of a planar magnetic transformer and second windings for a second side of the planar magnetic transformer. The PCB further includes conductive layers configured as the first windings, conductive layers configured as the second windings, and layers of an isolation material. Each layer of the isolation material is arranged between two conductive layers to provide electrical isolation between the two conductive layers. A group of two or more adjacent conductive layers are all conductive layers of the first windings and are all arranged between two conductive layers of the second windings. The thickness of the isolation material between the group of adjacent conductive layers of the first windings is less than the thickness of the isolation material between a conductive layer of the second windings and a conductive layer of the first windings.
