Bridgeless interleaved boost PFC converter with variable duty cycle control
(2011-12-28)
This paper proposes a bridgeless boost interleaved PFC (power factor correction) converter with variable duty cycle control. The application of bridgeless technique causes reduction of conduction losses, while the interleaving ...

Electronic compensation of inductive voltage dividers and standard voltage transformers
(IEEE, 1998)
A new compensating system is proposed to reduce the ratio error and the phase error of inductive voltage dividers and standard voltage transformers, operating at no load. An electronic amplifier reduces the input current, ...
The Impact of the Use of Large Non-Linear Lighting Loads in Low-Voltage Networks
(IntechOpen, 2019)

Fully-differential offset-cancelling circuit with configurable output common-mode voltage
(IEEE, 2013)
For certain applications, the offset voltage of the amplifiers represents a problem that must be addressed, since it may affect the transfer characteristics of the system. Offset memorization techniques allow to partially ...
A new design methodology for multipulse rectifiers with Delta auto-connected transformers and a retrofit application in Adjustable Speed Drives (ASDs)
(2012-12-01)
Multipulse rectifiers can replace a conventional six pulse three-phase rectifier (diode bridge) providing a DC voltage with low ripple, low Total Harmonic Distortion of current (THDi) and a high Power Factor (PF). In this ...
