摘要： A "PN junction device (ta) producing the Peltier effect and the Seebeck effect therein and a noise reducing effect". The PN junction device (ta) prevents the white noise included in the AC waveform of electric power supplied from a commercial AC power source and parasitic wave noise due to electromagnetic interference from adversely influencing the electromagnetic device supplied with the electric power and is effective when attached to an "electronic" functional circuit constituting a retrofitted or externally-fitted device at the designing or manufacturing stage. Such a PN junction device is applied to an "electric" circuit. At least one line of the lines between the AC power input terminal (IN) and the output terminal (OUT) connected to an electromagnetic device is branched to two parallel branch lines (a, b). In the branch circuits, series connection circuit comprising diodes (da, db) and PN junction devices (ta, tb) are connected to form an external device, thereby facilitating the use by the general user.

摘要： The invention in the simplest form is an improved hybrid power converter with uninterruptible power supply (UPS) and power quality capabilities as well as an integrated variable speed power source and control method that is used to generate high quality, uninterruptible AC power utilizing fewer batteries and operating at optimum fuel efficiency and with reduced emissions. The variable speed generator control scheme allows for load adaptive speed control of a power source such as an engine (20) and generator (10). The transformerless hybrid power converter topology and control method provides the necessary output frequency, voltage and/or current waveform regulation, harmonic distortion rejection, and provides for single-phase or unbalanced loading. The transformerless hybrid power converter also provides inline or offline UPS capability, line voltage and/or frequency sag and surge compensation, peak shaving capability, VAR compensation and active harmonic filtering.

摘要： An active current injection device (117) is used to generate and inject fundamental and non-fundamental frequency current components onto an AC power line (111). A current pump control circuit (132) receives an input signal which is representative of the line voltage of the power line. In response, the current pump control circuit (132) generates a control signal which is used to generate a current component at the fundamental frequency which lags the line voltage by approximately 90 degrees. This fundamental frequency current component is transmitted through an impedance (131) to the power line (111), thereby causing a voltage drop at the fundamental frequency across the impedance (131) which is within a selected range about the line voltage. This selected range is equal to approximately 25 to approximately 150 percent of the line voltage.

摘要： The invention relates to a hybrid filter for an alternating current network (6). The hybrid filter has a passive filter and an active filter (2,4) that are electrically connected in series, whereby the active filter (4) has a voltage source (8). According to the invention, a filter (14) adjusted to the nominal frequency of the alternating current network (6) is mounted electrically parallel to the active filter (4). This results in a hybrid filter for an alternating current network (6), whereby the active filter (4) is not subjected to fundamental frequency current component strain.

摘要： An active filter (4) for compensation of variations in an apparatus (3) current consumption from a power grid (1) as a cause of variations in the apparatus electrical load, through active frequency filtering and dynamic compensation of reactive energy/current. For each of the power grid's phases (a, b, c) the active filter comprises a transistor bridge (Ta, Tb, Tc) connected between each mentioned phase and a DC-link (7). The active filter comprises a filter circuit arranged to reduce disturbances on the power grid caused by the active filter of LCL-type. Preferably the active filter further comprises a control system (9) which comprises means in order to with a given working frequency (f) calculate point in time to which with said transistor bridges reverse the current direction through said DC-link, and said filter circuit is preferably adjusted to said working frequency.

摘要： A tuned filter for connection to a busbar in a high voltage electric power system. The filter incorporates a variable inductor (2); the variable inductor (2) comprising a main winding (4), auxiliary windings (6-12) and switching means (14-20) associated with each auxiliary winding (6-12). The auxiliary windings are arranged to act in inductive series with respect to the main winding, and the switching means (14-20) are used to selectively connect the auxiliary windings in electrical series with the main winding, so allowing the inductance of the inductor to be varied. To achieve enhanced variability of the inductance (2), each auxiliary winding (6-12) has a number of turns substantially equal to x2 (n-1) , where n is a positive integer corresponding to the position of each auxiliary winding in the inductive series (6-12) of auxiliary windings and x is also a positive integer. The switching means (14-20) are preferably constituted such that each auxiliary winding (6-12) is selectively connectable to the main winding (4) in any one of three connection modes, comprising a first connection mode in which the auxiliary winding assists the inductance of the main winding, a second connection mode in which the auxiliary winding opposes the inductance of the main winding and a third connection mode in which the auxiliary winding is bypassed with respect to the main winding.
