调节器拓扑电池供电系统-Regulator Topologi

Power supplies are perhaps the most crucial elements of a battery-powered system. Knowledge of some basic regulator topologies will help you select or design the right supply configuraTIons for your needs.



The parameters affecTIng the choice of a switching-regulator topology include the peak currents for the load and the inductor, the voltage level on the power transistors, and the necessity for magneTIc and capaciTIve energy storage. Table 1 shows the seven most common regulator topologies beginning with the simplest (top of table) (which are generally also the most desirable in terms of efficiency, cost, and size) and progressing to more specialized types (bottom). The table also lists the pros and cons of each topology, allowing you to scroll through and find the topology that meets your needs.
