A good rule for determining inductance is to allow the peak-topeakripple current to be approximately 30% of the maximum switch current limit. Also, make sure that the peak inductor current is below the maximum switch current limit. △I为peak-topeak ripple current Iout为 maximum switch current ...
Switching controller with reduced inductor peak-to-peak ripple current variationA switching controller having an over voltage protection circuit is disclosed. The over voltage protection circuit detects whether the output voltage is higher than an over voltage threshold and turns on the rectifier when ...
A current-fed dual active bridge dc-dc converter using dual transformers is proposed for the energy storage system and electric vehicles, which is suitable to be used in wide input and wide output voltage range bidirectional power flow applications. Optimized switching pattern and the coupling relati...
Analysis and Design of the Inductor-Current-Sensing Peak-Power-Tracking Solar-Array Regulator An analysis and design of a peak-power-tracking solar-array regulator that senses the inductor current are proposed. Because it uses the inductor current a... YJ Cho,BH Cho - 《Journal of Propulsion ...
In (60), ∆IL1 expresses the peak-to-peak changes in inductor current IL1. Furthermore, fS shows the switching frequency of the circuit in these equations. It should be mentioned that inductance values of L1, L2, and L3 are obtained when the switch is turned on: 𝐿1≥2𝐷𝑉𝑆...

to the level of the input voltage, substantially eliminating turn-on losses of the first FET. Control circuitry is provided for regulation of the power converter to control the peak-to- peak current in the inductor and to insure that at least a selected minimum value of the inductor current ...
mode, inductor peak-to-peak current is much lower than that of SEPIC converters and traditional buck/boost con- verters. Figure 2 shows the inductor current and switch node waveforms. Low inductor ripple current and the use of synchronous rectifiers allow the LTC3780 to achieve very high , LTC...
A load-dependant peak-current control single-inductor multiple-output (SIMO) DC-DC converter with hysteresis mode is proposed. It includes multiple buck an... MH Huang,KH Chen - IEEE Journal of Solid-State Circuits 被引量: 225发表: 2009年 A 200-mA, 93% peak power efficiency, single-induc...
In my opinion, the peak current flow through the inductor should be SQRT(25/4)*1.414=3.5A, so the inductor saturation current spec should be>3.5A. The RMS current flow through the inductor should be SQRT(25/4)=2.5A. So the temperature rise current spec should be >2.5A. Is that ...
