The sliding mode control of Variable Structure Systems has a unique role in control theories. First, the exact mathematical treatment represents numerous interesting challenges for the mathematicians. Secondly, in many cases it can be relatively easy to apply without a deeper understanding of its strong mathematical background and is therefore widely used in the field of power electronics. This...

Current mode control as usually implemented in switching power supplies actually senses and controls peak inductor current. This gives rise to many serious problems, including poor noise immunity, a need for slope compensation, and peak-to-average current errors which the inherently low current loop gain cannot correct. Average current mode control eliminates these problems and may be used effe...

Switch-mode power supplies represent a particular class of variable structure systems (VSS). Thus, they can take advantage of non-linear control techniques developed for this class of systems. In this paper the so called sliding mode control is reviewed and its application to switchmode power supplies is discussed. Sliding mode control extends the properties of hysteresis control to multi-varia...

INTRODUCTION This is the second in a series of application notes that define the fundamental behavior of MOSFETs, both as standalone devices and as switching devices implemented in a Switch Mode Power Supply (SMPS). The first application note (1) provided a basic description of the MOSFET and the terminology behind the device, including definitions and physical structure. This application note ...

The power supply designer is continually being pressured to provide units which have higher efficiency, better regulation, less EMI and RFI, and smaller size and weight, all at a lower cost. The solution to this problem is a combination of circuit topology, layout, and supply control. This application note will address output control techniques for linear and switch mode power supplies (SMPS). ...

Power gating technique reduces leakage power in the circuit. However, power gating leads to large voltage fluctuation on the power rail during power gating mode to active mode due to the package inductance in the Printed Circuit Board. This voltage fluctuation may cause unwanted transitions in neighboring circuits. In this work, a power gating architecture is developed for minimizing power in a...
