As we will soon see it is the relative value of the AC ripple,∆I, compared to the dc levels, I(DC), that is crucial to the transition in circuit conditions from the CCM to the DCM Usually this occurs at light loads where ∆V(ac) > V DC Since all switch mode power supplies can be operated open circuit

Chapter 5 The Discontinuous Conduction Mode

Discontinuous Conduction Mode (DCM) Occurs because switching ripple in inductor current or capacitor voltage causes polarity of applied switch current or voltage to reverse, such that the current- or voltage-unidirectional assumptions made in realizing the switch are violated Commonly occurs in dc-dc converters and rectifiers, having single-

1 Gallium Nitride (GaN) Technology Overview

AC-DC switching power supplies for early desktop computers were among the earliest volume consumers of power MOSFETs, followed by variable speed motor drives, fluorescent lights, DC-DC converters, and thousands of other applications that populate our daily lives

Designing Flyback Converters Using Peak-Current-Mode

discontinuous conduction mode (DCM) are treated individually Introduction This application note describes the methodology of designing flyback converters using the MAX17595/MAX17596 peak-current-mode controllers Flyback converters may be operated in discontinuous conduction mode (DCM) or continuous conduction mode (CCM) The component choices,
