... We can get a good approximation for r by using the following relationship. o r =V /I o A C The V , the Early voltage, is another parameter we must be given. It is typically in the A range of 50-100[V]. Note also that I is the dc value of the collector current. C With this, we can get a pretty good m ...

... The assumption that the output of op-amp U2 is saturated at V-sat when Vi-1 = 0 (no inhibition) means that G1G-2Vcth > 3.5 V. Using the relations between Vcth and Vth, between Vth and α, and between G1G-2 and nα, we find the restriction on the Hill coefficient n > 2.35(-V-sat − 1)/(imaxR) = 2.35(3.5 ...

Power electronics



Power electronics is the application of solid-state electronics to the control and conversion of electric power. It also refers to a subject of research in electronic and electrical engineering which deals with the design, control, computation and integration of nonlinear, time-varying energy-processing electronic systems with fast dynamics.The first high power electronic devices were mercury-arc valves. In modern systems the conversion is performed with semiconductor switching devices such as diodes, thyristors and transistors, pioneered by R. D. Middlebrook and others beginning in the 1950s. In contrast to electronic systems concerned with transmission and processing of signals and data, in power electronics substantial amounts of electrical energy are processed. An AC/DC converter (rectifier) is the most typical power electronics device found in many consumer electronic devices, e.g. television sets, personal computers, battery chargers, etc. The power range is typically from tens of watts to several hundred watts. In industry a common application is the variable speed drive (VSD) that is used to control an induction motor. The power range of VSDs start from a few hundred watts and end at tens of megawatts.The power conversion systems can be classified according to the type of the input and output power AC to DC (rectifier) DC to AC (inverter) DC to DC (DC-to-DC converter) AC to AC (AC-to-AC converter)
