For pt.I see ibid., p.2504-11 (1999). This paper presents a general control approach to achieve power-factor-correction (PFC) for three-phase boost rectifiers with center-tapped or split DC output capacitors. These rectifiers can be decoupled into a series-connected dual-boost topology during each 60° of line cycle although they have different configurations. A new extension of constant freque...

A typical industrial power network may consist up to hundreds of pieces of equipment and requires even more protection relays to protect the system. Each protection relay in the power network needs to be coordinated with the relays protecting the adjacent equipment. The overall protection coordination is thus very complicated. A new concept of protection coordination by time is introduced in this ... View full abstract»

| | PDF (436 KB)

A reciprocating compressor with a rotary motor which is used in a refrigerator has low efficiency, since it has large mechanical losses due to the crank mechanism. In a free piston linear compressor with linear motors, the mechanical losses of the crank mechanism can be decreased and system efficiency improved. However, the compressor will fail and the system efficiency will be reduced if the pist... View full abstract»
