A power factor correction circuit comprising: a global voltage input; and means for deriving a reference current from the global voltage; whereby the means for deriving the reference current comprises a leading phase admittance cancellation, LPAC, transfer function and a filter, whereby the reference current is derived from a sum of an output of the LPAC transfer function and an output of the filter.

Power converter power factor control

A modular electric power converter includes a plurality of power converter modules, each module comprising a cell of a Modular Multilevel Converter, MMC, to provide a controlled ac output.

Power converter

A power factor correction circuit comprising: a global voltage input; and means for deriving a reference current from the global voltage; whereby the means for deriving the reference current comprises a digital leading phase admittance cancellation, DLPAC, transfer function and a filter, whereby the reference current is derived from a sum of an output of the DLPAC transfer function and an output of the filter, and further comprising means for compensating for delays in the DLPAC function.

An integrated single stage ac-dc driver for powering LED loads includes a boost converter operating in a Discontinuous Conduction Mode, DCM, comprising a half-bridge, and a Zeta Asymmetrical Half Bridge, ZAHB, integrated with the boost converter such that the boost converter and the ZAHB share the half-bridge to perform power factor control, PFC, with a fixed duty cycle and control an output voltage.

Low weight isolated integrated single-stage AC-DC LED driver

A damper for a power train, comprising a piezoelectric transformer and a load element connected across the output of the piezoelectric transformer.
