SIMULATION FOREGROUN D READING Back Bay Battery, Inc. Overview The battery industry is enormous, with worldwide revenues of approximately $45 billion. It is highly fragmented with at least 20 major manufacturers in each technology segment. Because of the wide range of applications of batteries, companies have tended to specialize in a particular technology or market application. Disposable batteries, such as the widely available carbon-zinc and alkaline cells, are available in standard sizes

DESIGN OF SNUBBERS FOR POWER CIRCUITS By Rudy Severns What’s a snubber? Power semiconductors are the heart of power electronics equipment. Snubbers are circuits which are placed across semiconductor devices for protection and to improve performance. Snubbers can do many things: · · · · · · Reduce or eliminate voltage or current spikes Limit dI/dt or dV/dt Shape the load line to keep it within the safe operating area (SOA) Transfer power dissipation from the switch to a resistor or a useful load Reduce
