    摘要: A heavy duty cycle power converter (2) has current mode control in which the closed loop control is carried out by a controller (5) using a desired signal (11) which is a function of the difference between the desired duty cycle (7) and the measured duty cycle (6) This fluctuates current mode control without voltage feedback.

    摘要: A PCB assembly (1) in this case a DC-DC converter comprising a single layer board (2), mounts power semi-conductor devices forming high heat generating components (3) and various cores of magnetic material forming heat dissipating components (4). Tracks of heat conductive coupling material (6) lie above or below each heat generating component (3) and project into one of the heat dissipating components (4) and beside the others. In one embodiment, the heat generating components (3) are housed within a heat dissipating component (3). In another PCB assembly, there is an additional plug-in PCB which may itself carry heat generating components (3) or only heat dissipating components (4). In the latter case, the heat generating components (3) are mounted on the PCB assembly below the additional plug-in PCB.

    摘要: This invention relates to a power converter (1) comprising a converter input (3), a converter output (5), a power factor correction (PFC) stage (7) and an isolation stage (9). The PFC stage (7) is implemented by way of a buck PFC with low side drive and low side current sensing, There is provided a third stage, an intermediate buck pre-regulation stage (11), intermediate the buck PFC stage (7) and the isolation stage (9), Control of the power converter output voltage is achieved by varying the duty cycle of the intermediate buck pre-regulation stage (11) and therefore the isolation stage (9) may be an unregulated stage operated as a fixed DCDC voltage converter. The isolation stage (9) is operated as a 50%-50% duly cycle double ended stage. The configuration of power converter allows for a relatively inexpensive, highly efficient converter with 90%+ efficiency and simplified control.

    摘要: This invention relates to an ACDC converter (1) comprising a converter input (3) and a converter output (5), a pre-regulation stage (7) and a DC transformer stage (9) comprising a transformer input stage (11) and a transformer output stage (13). The transformer input stage comprises a double ended converter and there is further provided a controller (17) for providing a control signal to the double ended converter. The controller (17) operates the ACDC converter using burst mode control and by sending control signals comprising pulse sets that are designed to provide substantially zero net magnetising current in the double ended converter. The pre-regulation stage preferably comprises a buck converter which in turn also provides power factor correction to the input of the ACDC converter.

    摘要: This invention relates to a power converter (1 ) comprising a converter input (3), a converter output, a power factor pre-regulation stage (5), an isolation stage (7) and a control unit (9). The power factor pre-regulation stage (5) further comprises a buck power factor correction (PFC) circuit (15) and a bulk capacitor (25) fed by the buck PFC circuit. The amount of line current provided to the bulk capacitor (25) by the buck PFC circuit (15) may be adjusted according to the converter requirements in order to keep the voltage across the bulk capacitor (25) sufficient to ensure uniform operation of the power converter. Monitoring of the voltage across the bulk capacitor (25) and monitoring of the isolation stage (7) output current is provided to determine when additional current is to be applied to the bulk capacitor (25) and to ensure the power converter (1 ) operates within pre-defined parameters.
