摘要： A method and inverter (2, 27) for converting a DC input voltage supplied by a DC source (9), which is in particular a solar cell array, into a 3-phase AC output. For each phase (R, S, T) the DC input voltage is converted to a DC output voltage (DCR, DCS, DCT) with a specific waveform. The waveforms of the three DC output voltages are identical, shifted in time by 120° to each other and they are such that by subtracting any two of them a sinusoidal waveform is obtained. The waveform of each DC output voltage may comprise a first portion of ⅓ or 120° of the AC output cycle with an amplitude of zero and a subsequent second portion of ⅔ or 240° of the AC output cycle during which the DC output voltage has a non-zero amplitude.

摘要： Ein Wechselrichter zur wahlweisen Einspeisung von Wirk- und Blindleistung in ein Versorgungsnetz weist zwei in Reihe geschaltete Zwischenkreiskondensatoren (C1, C2) auf, deren gemeinsamer Anschluss ein mittleres Spannungsniveau (0V) zwischen einem positiven Spannungsniveau (+Uz) und einem negativen Spannungsniveau (-Uz) definiert. Er weist außerdem erste, zweite, dritte und vierte Halbleiterschalter (S1, S2, S3, S4) mit jeweils parallel geschalteten Freilaufdioden auf, die seriell in dieser Reihenfolge zwischen dem positiven und dem negativen Spannungsniveau liegen, wobei der gemeinsame Anschluss (SWP) des zweiten und dritten Halbleiterschalters (S2, S3) über eine Drossel (L1) mit dem Versorgungsnetz (Uac) verbunden ist. Der Wechselrichter weist außerdem in Reihe geschaltete erste und zweite Dioden (D1, D2) auf, deren gemeinsamer Anschluss auf dem mittleren Spannungsniveau (0V) liegt, und deren jeweils zweiter Anschluss mit dem gemeinsamen Anschluss des ersten und zweiten Halbleiterschalters (S1, S2) bzw. des dritten und vierten Halbleiterschalters (S3, S4) verbunden ist. Gemeinsame Anschlüsse (A12, SWP, A34) von je zwei der ersten bis vierten Halbleiterschalter (S1, S2, S3, S4) sind mit zusätzlichen Drosseln (L2, L3, L4, L5) verbunden, die mittels zusätzlicher Halbleiterschalter (S5, S6, S7, S8, S9) schaltbare Pfade zur Übernahme von Freilaufströmen bilden. Auf diese Weise kann eine Belastung von Dioden durch den Reverse-Recovery-Effekt vermieden werden.

摘要： Floating electrically isolated active impedance modules are formed to attach to power transmission lines without breaking the lines such that the power line forms a secondary of the main transformer of the module. Each module includes an electrical energy storage device and a switching circuit, such as a single phase inverter, connected to the storage device and to the main transformer primary winding. The inverter can be controlled to couple a selected voltage to the transmission line through the main transformer primary winding which can provide effective positive impedance, negative impedance, or a voltage at or near phase quadrature with the line current. Many active impedance modules may be distributed over a power system grid to allow control of the impedance of the power lines in the grid and to steer power through the grid, with each module electrically isolated from ground and from other phase lines of the transmission system.

摘要： Tunneling-effect converters of thermal energy to electricity with an emitter and a collector separated from each by a distance that is comparable to atomic dimensions and where tunneling effect plays an important role in the charge movement from the emitter to the collector across the gap separating such emitter and collector. At least one of the emitter and collector structures includes a flexible structure. Tunneling-effect converters include devices that convert thermal energy to electrical energy and devices that provide refrigeration when electric power is supplied to such devices.

摘要： This invention relates to a power converter (1) comprising a converter input (3), a converter output (5), a power factor correction (PFC) stage (7) and an isolation stage (9). The PFC stage (7) is implemented by way of a buck PFC with low side drive and low side current sensing, There is provided a third stage, an intermediate buck pre-regulation stage (11), intermediate the buck PFC stage (7) and the isolation stage (9), Control of the power converter output voltage is achieved by varying the duty cycle of the intermediate buck pre-regulation stage (11) and therefore the isolation stage (9) may be an unregulated stage operated as a fixed DCDC voltage converter. The isolation stage (9) is operated as a 50%-50% duly cycle double ended stage. The configuration of power converter allows for a relatively inexpensive, highly efficient converter with 90%+ efficiency and simplified control.

摘要： A switched mode power supply comprises a first switch coupled to an input power source, a second switch coupled to ground, and an output filter coupled to a phase node defined between the first and second switches. The first and second switches are responsive to a pulse width modulated signal to thereby regulate power provided to the output filter. A controller is provided in a feedback loop that monitors operation of the first and second switches and delays activation of one of the first and second switches to preclude simultaneous conduction. The controller comprises at least one delay control circuit adapted to delay delivery of the pulse width modulated signal to at least one of the first and second switches. The delay control circuit detects a phase difference between state transitions of the first and second switches and provides a delay corresponding to a magnitude of the phase difference.

摘要： A breakaway power supply device operatively connectable to an electronic appliance either directly or indirectly via a controller is provided. The controller is used for sensing and/or controlling the operation of the appliance to which it is operatively connected. The breakaway device also has a power cord with a first connector suitable for releasably connecting with the controller and/or the appliance via a magnetic attraction. The power cord also has a second connector suitable for connecting to a power source. The magnetic attraction is suitable to withstand a predetermined or predefined disconnect force. The predetermined disconnect force may be varied as desired. The breakaway power supply device provides an effective, reliable and safe power connection for heatable electronic appliances that require continuous intimate contact with a separable controller.
