Power Electronics
Power electronics is the segment of electronics whose purpose is to convert or condition electrical power from one form (that which is available) to another form (that which is needed) through the use of power semiconductors and other more traditional types of electrical components. Power electronics products and systems are found throughout the generation, distribution and use of electrical power.
The combined worldwide market for power electronics products exceeds $70 billion annually. Important segments of the market include the following:
 | Variable frequency motor drives for automation ($12 billion) |
| Power supplies for instruments and computers ($16 billion) |
| Uninterruptible power supplies, active filters and other power quality products ($10 billion) |
| Propulsion systems for electric and hybrid vehicles |
| Converters for renewable and alternative power, such as wind turbines, hydro turbines, generator sets, photovoltaic cells, fuel cells and microturbines ($4 billion) |
| Power conditioners for energy storage systems, such as flywheels, super capacitors and batteries |
| Welders |
| Industrial power supplies for metal heating and plating |
While power electronics products cover a broad power range from watts to hundreds of megawatts, Peregrine is interested primarily in medium power applications, that is, applications between one kilowatt and one megawatt.
Many sophisticated technologies contribute to the success of power electronics products and systems. The following chart shows some of these.
