The purpose is to alternate the inductor current between the switch and diode, so that it always has a path to flow in. Otherwise the converter would get destroyed by the resulting voltage spike (see Figure 1.6 again). In all topologies, when the switch conducts, it associates the inductor...
The purpose of the transient simulation is to verify that the impedance is sufficient over the expected range of pulse duration conditions.Because the inductor simulation is in the time domain (transient), a model with Laplace elements is not appropriate. To capture the impedance, a time-domain ...
The previous circuits have largely avoided such nonlinearities, but they can be exploited to produce chaos, much like the circuits in Chapter 6 used the saturation of operational amplifiers for that purpose. This short chapter describes nonlinear inductors and gives three examples of circuits that ...
Power Factor Correction Circuits Issa Batarseh Ph.D., Huai Wei Ph.D., in Power Electronics Handbook (Third Edition), 2011 19.5 DCM Input Technique To get rid of the complicated control circuit invoked by CCM shaping technique and reduce the cost of the electronic interface, DCM input technique...

Description of the Related Art Many digital and analog elements and circuits have been successfully applied to semiconductor integrated circuits. Such elements may include passive co...
In some embodiments, the first inductor Lsa has a first terminal coupled to the outputs of circuits 102-1 through 102-N and a second terminal coupled the first programmable resistor R1a, which is coupled to a supply rail Vdd2. In some embodiments, the second inductor Lsa has a first ...
in the field of power electronics. Such circuits are designated as power conditioners, converters, inverters, power supplies and motor controls. Essentially, these particular circuits as well as many others operate to control or distribute power in a specified environment and for a particular purpose...
The sole purpose of the high permeability core mate- rial is to provide an easy, low reluctance flux path to link the energy stored in the gap to the winding, thus efficiently coupling the energy storage location (the gap) to the external circuit. In performing this critically important ...
Place the inductor and diode as close as possible to the switch pins to minimize noise coupling into other circuits. Use a common ground node for power ground and a different one for control ground (AGND) to minimize the effects of ground noise. Connect these ground nodes together (star ...
