The free-wheel diode's anode connects to ground through the controller. A small-value current-sense resistor and amplifier measure the diode current. The combined sense-resistor/amplifier scale factor ...

Switch-mode power supplies can use digital current-mode techniques for protection against peak currents, magnetic field "ratcheting," and input-voltage variations. Digital control of switch-mode ...

Fig 1. The buck converter schematic shows the voltage feedback loop and the fast peak CMC loop. The current waveform as seen by the shunt is the dominant signal at the ramp of the PWM comparator.

4th course in the Modeling and Control of Power ElectronicsInstructor: Dragan Maksimovic, Ph.D., Professor The course is focused on current-mode control techniques, which are very frequently applied ...

Average Current-Mode Control of DC-DC Power Converters is a must-have reference and guide for researchers, advanced graduate students, and instructors in the area of power electronics, and for ...

Summary <p>The average current&#x2010;mode controlled boost converter is an attractive choice due to the combined advantages of the power&#x2010;stage and control method. This chapter develops the ...

In addition, since the LTC3866 uses constant frequency peak current mode control architecture, it guarantees cycle-by-cycle peak current limit and current sharing between different power supplies. It ...

Thus, a current-mode regulator can be much more easily compensated and thus stabilised. Fig. 2 shows the simple transfer function of the power stage of a typical current-mode regulator. Fig. 2: A ...

The UC1846 control IC provides all of the necessary features to implement fixed-frequency, current-mode control schemes, while maintaining a minimum external parts count. The superior performance of ...

Using tail current sources/mirrors instead of resistors has been standard since the 1960’s, see uA709, for example. Larger CM range, better CMR, constant tail current, much easier to produce ...
