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 controller for use in a power converter includes a comparator that receives an output signal representative of an output voltage of the power converter. The comparator generates a constant voltage signal in response to a comparison of the output signal and a reference signal. A switch request circuit receives the constant voltage signal and a fault signal. The switch request circuit generates a request signal in response to the constant voltage signal and the fault signal to control switching of a power switch of the power converter to control a transfer of energy from an input of the power converter to the output of the power converter. A power limit fault circuit receives the request signal. The power limit fault circuit generates the fault signal to indicate a fault existence in the power converter in response to a rate of consecutive request pulses greater than a threshold.

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： Pulse sharing control to enhance performance in multiple output power converters is described herein. During a switching cycle, an energy pulse is provided to more than one port (i.e., output) using pulse sharing transfer. Pulse sharing transfer may enhance performance by reducing audible noise due to subharmonics and by reducing a root mean square current of one or more secondary currents. A primary switch is closed to energize an energy transfer element via a primary current. Energy may be shared among a first load port on a first circuit path via a first secondary current and among a second load port on a second circuit path via a second secondary current.

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： Methods and apparatus for continuous conduction mode operation in multi-output power converters are described herein. During a switching cycle, secondary current may be delivered via a diode to a secondary output. Prior to beginning a subsequent switching cycle, a diverting current may be provided to a lower voltage secondary output on a parallel path. In this way diode current may be reduced to substantially zero prior to the subsequent switching cycle.

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.
