摘要： A method of dynamically adjusting a storage time of a bipolar junction transistor (BJT) in a switched mode power converter during a switching cycle includes generating a storage time reference signal responsive to an input voltage signal. A collector off signal is generated responsive to a comparison of a current sense signal to a collector off reference threshold signal. The current sense signal is representative of a switch current of the BJT. A base off reference threshold signal is generated responsive to the storage time reference signal and the collector off signal. A base off signal is generated responsive to a comparison of the current sense signal and the base off reference threshold signal. Charging of a base terminal of the BJT is discontinued responsive to the base off signal, and the base terminal of the BJT is discharged responsive to the collector off signal.

摘要： A boost-bypass converter includes a boost inductor coupled between an input and an output of the boost-bypass converter. A bypass diode is coupled between the input the output of the boost-bypass converter. A boost switching element is coupled to the boost inductor, and is coupled to be activated during a first interval in each line half cycle of an input voltage to boost an output voltage at the output of the boost-bypass converter. The boost switching element is coupled to be deactivated during a second interval in said each line half cycle such that the output voltage drops towards the input voltage. The output voltage is coupled to follow the input voltage during a third interval in said each line half cycle of the input voltage. Energy is transferred between the input and the output of the boost-bypass converter through the bypass diode during the third interval.

摘要： Apparatus and methods for sequencing outputs in a multi-output power converter system are disclosed herein. During start-up multiple CC/CV outputs may be sequenced so that energy is first provided to a highest voltage secondary output and subsequently provided to a lowest voltage secondary output. Additionally, control may be exerted so as to concurrently and monotonically increase voltages during at least part of the start-up transient; and concurrent control may be further implemented using control circuitry and a variable reference generator. In some embodiments a variable reference may be generated from a capacitor voltage.

摘要： A switched mode power converter has an energy transfer element that delivers an output signal to a load. A power switching device coupled to the primary side of the energy transfer element regulates a transfer of energy to the load. A secondary controller is coupled to receive a feedback signal and output a pulsed signal in response thereto. A primary controller is coupled to receive the pulsed signal and output a drive signal in response thereto, the drive signal being coupled to control switching of the power switching device. A compensation circuit generates an adaptively compensated signal synchronous with the pulsed signal. The adaptively compensated signal has a parameter that is adaptively adjusted in response to a comparison of the feedback signal with a threshold reference signal. The parameter converges towards a final value that produces a desired level of the output signal.

摘要： A control system for use in a power converter having a plurality of outputs comprising a primary switching control block, a secondary control block, and a multi-output control block. The primary switching control block is coupled to control switching of a primary switch. The secondary control block is coupled to control switching of a synchronous rectifier switch. The multi-output control block is coupled to control switching of at least one pulse transfer switch coupled to one of the plurality of outputs. A request for an energy pulse is transferred to the primary switching control block to turn ON the primary switch to transfer the energy pulse to one of the plurality of outputs. The multi-output control block comprises an interface to send the request for the energy pulse and to receive an acknowledge signal to and from the secondary control block.

摘要： A power converter includes a primary winding and multiple output windings to provide multiple independently controlled and regulated outputs with a common return line. The outputs are coupled to independently regulate constant current, constant voltage, or both constant current and constant voltage outputs. A secondary control block is coupled to control a synchronous rectifier switch coupled to the common return line to synchronize switching with a primary side power switch to provide complementary conduction of the primary winding and the multiple output windings. A plurality of controlled power pulse switches is coupled to the multiple output windings. A request of a power pulse from each of the outputs is transferred through the secondary control block to a primary switch control block to turn on the primary side power switch to transfer a power pulse to the multiple output windings and through controlled power pulse switches to the outputs.
