摘要： A primary-side sampled feedback system includes a sample acquisition phase during which the voltage across the clamp capacitor is sensed as a measure of the primary-reflect output voltage. One end of the clamp capacitor is ground-referenced during the sample acquisition phase. The sample circuitry, which may include a transformer-coupled input for receiving the gate drive of the secondary switch, may use primary side, secondary-side, or primary and secondary side signals to generate the sample acquisition control pulse and clamp switch drive signal. The sample acquisition control pulse occurs when the secondary current reaches its minimum or zero.

摘要： A transformer-coupled buck-boost DC-DC power converter is disclosed. An active clamp circuit is provided to form a resonant circuit with the transformer to control the slew rate of the secondary current and allow the secondary switch to be turned ON at conditions of zero voltage and relatively low current. The characteristic resonant period of the active clamp transformer circuit may be less than the minimum converter operating period. A winding of the transformer is shunted during a clamp phase to retain energy in the transformer. ZVS phases are provided to reduce switching losses when switches in the converter are turned ON. An energy-storage phase may be varied to control the amount of energy stored per operating cycle. An input-storage phase may transfer energy to the clamp capacitor during a series of converter operating cycles and transfer said energy to the secondary during different converter operating cycles.

摘要： A droop compensation system includes a controlled current source that provides a scaled model of the PRM output current or VTM input current on an interface connection. A controlled resistance modeling the VTM effective series input resistance is connected across the interface terminal. The voltage developed across the controlled resistance by the controlled current establishes a correction signal representative of the VTM droop that is used to adjust the PRM output thereby compensating for the droop. A VTM control interface provides a mechanism for enabling and disabling the VTM. The VTM control circuitry may be powered by the interface connection, allowing the VTM to operate and process power when the VTM input voltage is below its normal minimum operating voltage, increasing the VTM dynamic range and allowing “soft start” into a capacitive load.
