Differential-Mode EMI Reduction in a Multiphase DCM Flyback Converter

Multiphase Bidirectional Flyback Converter Topology for Induction Motor Drive

For hybrid electric vehicles, the batteries and the drive dc link may be at different voltages. The batteries are at low voltage to obtain higher volumetric efficiencies, and the dc link is at higher voltage to have higher efficiency on the motor side. Therefore, a power interface between the batteries and the drive’s dc link is essential. This power interface should handle power flow from batt...

Controlling EMI with A Chaotic Peak Current-mode Boost Converter

In this paper, a novel boost converter is designed where its current mode control is dependent on two reference currents and an external clock. A detailed study on its dynamics is carried out based on its corresponding current mapping function. As demonstrated in both simulations and experiments, by operating the proposed boost converter in its chaotic mode, the electromagnetic interference can...

Interleaved Dcm Single-stage Pfc Converter with Reduced Emi and Boost Inductor Sizes

Active-Clamping Quad-Flyback Converter

An active-clamping quad-flyback converter is proposed to achieve zero voltage switching (ZVS) for all power switches. The secondary sides of quad-flyback converter are connected in parallel to share the load current. Thus, the transformer copper losses and the conduction losses on the output diodes are reduced. Activeclamping part including one auxiliary switch and one clamp capacitor can relea...

Average Model of Boost Converter , including Parasitics , operating in Discontinuous Conduction Mode ( DCM ) A

This paper presents the principles of state-space average modeling of DC-DC Boost converters operating in the Discontinuous Conduction Mode (DCM) which occurs in converters due to low load current operation. The switching ripples in inductor current or capacitor voltage cause polarity reversal of the applied switch current or voltage and thus a zero current mode is reached. Modern converters ar...
