摘要： It provides a DC to DC converter(1) with intermediate conversion into AC power, including: a transformer (Tr) having a primary winding (Wp) and a secondary winding (Ws)；a first DC to AC conversion circuit (S1,S2,S3,S4) having its AC terminals coupled with the primary winding (Wp) of the transformer (Tr)；a first AC to DC conversion circuit (D11, D12, D13, D14) having its AC terminals coupled across a first tap (T1) and a second tap (T2) of the secondary winding (Ws)of the transformer (Tr)；a second AC to DC conversion circuit (D21, D22, D23, D24) having its AC terminals coupled across a third tap (T3) and a fourth tap (T4)of the secondary winding (Ws) of the transformer (Tr), wherein the first tap (T1)and the second tap (T2) are arranged between the third tap (T3) and the fourth tap (T4) along the secondary winding (Ws) of the transformer(Tr); and at least one first power switch (SU,SL), being arranged between one of DC terminals of the first AC to DC conversion circuit (D11, D12, D13, D14) and one of DC terminals of the second AC to DC conversion circuit (D21, D22, D23, D24). By having the solution as above, the DC output voltage may be changed between two levels by operating only one power switch. Because a power switch is more expensive than a multiple of power diodes, by reducing the number of power switches responsible for changing the level of DC output voltage, it is helpful for decreasing the cost and complexity of control. Besides, the power loss can be decreased due to switching of less power switch.

摘要： Described is a hybrid electronic and magnetic structure that enables a transformer with fractional and reconfigurable effective turns ratios (e.g. 12:0.5, 12:2/3, 12:1, and 12:2) and hereinafter referred to as a Variable-Inverter-Rectifier-Transformer (VIRT). A VIRT is valuable in converters having wide operating voltage ranges and high step-up/down, as it offers a means to reduce turns count and copper loss within a transformer while facilitating voltage doubling and quadrupling. Such characteristics are beneficial for reducing the size of a transformer stage in many power electronics applications, such as USB wall chargers. In embodiments, a VIRT comprises a plurality of switching cells distributed around a magnetic core and coupled to half-turns wound through that core. By controlling operating modes of the switching cells, it is possible to gain control over flux paths and current paths in the transformer.

摘要： A synchronous rectifier using only n-channel devices in which the low-side switches are effectively cross-coupled using low-side comparators and the high-side switches perform an accurate zero-voltage-switching (ZVS) comparison. The charging path of each bootstrap domain is completed through the low-side switches, which are each always on for every half-cycle independent of loading. This scheme gives rectifier efficiency gain because a) each bootstrap domain receives maximum charging time, and b) the charging occurs through a switch rather than a diode. Both these factors ensure the bootstrap domain is fully charged, thereby reducing conduction losses through the rectifier switches. Furthermore, settings may be adjusted by software to optimize the resistive and capacitive losses of the rectifier. Using data for die temperature and operating frequency, software can create a feedback loop, dynamically adjusting rectifier settings in order to achieve the best possible efficiency.

摘要： A controller (20; 21; 22) used to control a flyback switching mode power supply (10; 11; 12). The flyback switching mode power supply (10; 11; 12) is constructed to charge a capacitor (C), and includes a rectifying device (RD), a series arrangement of a switch (SW1) and a primary winding (L1) of a transformer (T) for receiving an input voltage (Vin), and a secondary winding (L2) of the transformer (T) for charging the capacitor (C) via the rectifying device (RD) to an output voltage (Vout). The controller (20; 21; 22) is configured to sense the output voltage (Vout) and to turn on the switch (SW1) when the change of the output voltage (Vout) over time becomes smaller than a predetermined threshold (dth). By using the controller (20; 21; 22) to sense and use the output voltage (Vout) across the capacitor (C) to turn on the switch (SW1), a controlled flyback switching mode power supply (10; 11; 12) that makes use of voltage control is realized.

摘要： A switching amplifier realizes bidirectional energy flow and combines switching and power amplification into one single stage so as to increase system efficiency. The modulator circuit of the amplifier receives and modulates an input signal, and generates and outputs modulated driver signals, which are used by the power driver circuit to generate signals to drive switching transformers of an amplifier circuit of the amplifier, and control signals, which are used to control and output generator circuit so as to allow individual inductors across the load by enabling current flowing through the load to have a path to ground. The amplifier circuit comprises switching transformers as well as circuitries configured to capture energy returned from the load and enable the captured energy to flow back to a power supply circuit of the amplifier through an energy flow-back circuit of the amplifier.
