In a circuit???oriented simulation environment, there are three levels of modeling: component level, circuit level and system level. A system???level simulation can merge the interaction of different modules in a system, for example, a converter, a controller, source, and load. A very appropriate level of circuit???level modeling must be chosen to incorporate the functionality and large signal behavior of switching converters, fast inner control loops, and fundamental power electronic switch operation. The PSIM circuit simulator approaches the idealized switching of semiconductors instead of detailed physical models with a good degree of analog and digital circuits required for designing circuits. A simple circuit that can be studied in a circuit simulator is a half???wave rectifier, because it can be used for cross???examination of exact mathematical calculations with their simulations in a circuit simulator as well as their numerical computation using a platform such as MATLAB.

Hybrid and Series Active Filters
The series active filter acts like a dual device for the shunt active filter. The shunt active filter has a voltage source at the source side and a current source at the load side, where the current source includes harmonic currents that have to be compensated by the shunt active filter. In some cases, the combination of a voltage source and its impedance at the source side is considered as a current source. As a result, the series active filter operates as a dual circuit of the shunt active filter from a theoretical point of view. Comprehensive research has been conducted on hybrid active filters for harmonic filtering, harmonic damping, harmonic isolation, and harmonic termination. This chapter presents a transformer less hybrid active filter integrated into a medium???voltage motor drive for energy savings. It discusses the stability of the ac/dc power conversion system characterized by integration of a series active filter with a double???series diode rectifier.

Some Results on Ideal Rectifier CircuitsBell Laboratories Memorandum, June 8, 1955.
Some results are obtained in the theory of circuits constructed of rectifiers and of rectifiers and relay contacts. Such circuits are shown to be related to partially ordered sets. Upper and lower bounds are found for the number of rectifiers necessary for nterminal rectifier circuits. A duality theorem is obtained. A partly ordered set analyzer is described.

The primary sources of harmonics in the power system are power converters, rectifiers, inverters, diacs, triacs, gate turn off thyristors (GTOs) and adjustable speed drives. The characteristic harmonics are those produced by the power electronic converters during normal operation and these harmonics are integer multiples of the fundamental frequency of the power system. The singlephase rectifier fullbridge circuit is first considered to establish relations on the AC and DC sides and origin of harmonics. The reactive power consumed by the converters can be supplied by shunt capacitors and filters. The thyristorbased converters become economical in large power handling capabilities as per device basis; the thyristors can handle two to three times more power than GTOs, integrated gate bipolar transistors (IGCTs) and MOS turnoff thyristors (MTOs). Conventional thyristors have turnon control only. These can be only current source converters.
