    摘要： The present disclosure relates to methods, a system and a module for operating a power converter module. The power converter module comprises a voltage converter, an output circuitry, and a processing circuitry operable for controlling the voltage converter. One method comprises transmitting a first status signal representing operating parameters of the voltage converter to the processing circuitry. Determining whether the first status signal of the voltage converter is acceptable. The method also comprises transmitting a second status signal representing the operating parameters of the output circuitry to the processing circuitry. The method also comprises determining if the second status signal is above a predetermined threshold value. When the second status signal is above said predetermined threshold value and the status of the voltage converter is acceptable, entering a peak output mode operating the voltage converter at maximum power dissipation.

    摘要： An isolated switched mode power supply comprises a transformer, with primary and secondary windings, and a rectification network connected to the secondary winding. The rectification network and the transformer are arranged such that, during a free-wheeling period of operation of the switched mode power supply, a magnetic flux from a first portion of a secondary winding of the transformer substantially cancels a magnetic flux from a second portion of the secondary winding between the first and second portions of the secondary winding. Additionally, a secondary side circuit connected to the secondary winding comprises a switching device, which is connected to a center-tap, provided between the first and second portions of the secondary winding, and an output of the rectification network so as to conduct at least a part of a free-wheeling current flowing in the secondary side circuit during the free-wheeling period.

    摘要： A digital control unit generates a control signal to control a duty cycle of a switched mode power supply such that a faster response to an input voltage transient is achieved. The digital control unit comprises a feedback compensator, a feed forward compensator, a transient detector, and a controller. The transient detector receives a signal indicative of the input voltage of the switched mode power supply and detects transients on the received signal. The feedback compensator receives a signal indicative of the output voltage of the switched mode power supply and adjusts the control signal. The feed forward compensator receives a signal indicative of the input voltage of the switched mode power supply, performs a relatively fast, but coarse, adjustment of the control signal, and then performs a more accurate, but relatively slow, adjustment of the control signal.

    摘要： A switched mode power supply (SMPS) comprising a feedback unit, voltage feed forward (VFF) compensation signal generator and a transient detector. A VFF compensation signal is only applied to the output of the feedback unit when a transient is detected by the transient detector on the input voltage of the SMPS, thereby saving power and computation time. The transient detector comprises a first comparator to detect that a positive transient has occurred if a difference signal is greater than a positive threshold level; a second comparator to determine if the difference signal is within a predetermined range of positive values and output a result that indicates if the difference signal is within the predetermined range of positive values; and a first calculator to detect that a positive transient has occurred if, out of a first predetermined number of consecutive results of the output of the second comparator, there is at least a second predetermined number of results indicating that the difference signal is within the predetermined range of positive values. The transient detector comprises further features for similarly detecting a negative transient.
