摘要： Current flow in a transistorized series resonant inverter is switched in an inherently simple and stable manner by time integrating the difference between the electrical output and a reference and varying the switching frequency of the inverter so as to null the time integrated difference in a feedback control loop. Each transistor is on for about half the resonant period of the tank circuit so that it is cut off at or slightly after the zero-crossing of the sinusoidal collector current.

摘要： A signal generator (50A) for producing, from a low voltage power supply, relatively large magnitude pulse signals of opposite polarity to a device (10) input terminal having a parallel resistor (11)-capacitor (12) circuit connection to a reference voltage is disclosed. A voltage multiplier (52) powered by the low voltage power supply provides a multiplied voltage output which is stored on a first large capacitor (58). A second large capacitor (59) has one terminal connected to the device (10) input terminal. To produce the large, opposite polarity signals, a control circuit means operates in conjunction with the voltage multiplier (52) and the first capacitor (58) to produce a predetermined sequence of voltages on the second terminal of the second capacitor (59).

摘要： The invention provides an inverter using field effect transistors (F.E.T.'s). One load terminal is connected via a first F.E.T. to a positive supply terminal and via a second F.E.T. to a negative supply terminal. The other load terminal is connected via a third F.E.T. to the positive supply terminal and via a fourth F.E.T. to the negative supply terminal. A first control switching waveform is applied to the gate electrode of the second F.E.T. and, via polarity inverting means, to the gate electrode of the first F.E.T. A second control switching waveform is applied to the gate electrode of the fourth F.E.T. and, via polarity inverting means, to the gate electrode of the third F.E.T , whereby as the first and fourth F.E.T.'s are switched off said second and third F.E.T.'s respectively are switched on, and vice versa. Means are provided for biasing the first and third F.E.T.'s positively with respect to the positive supply terminal when the respective F.E.T. is in a conducting condition.

摘要： Transistorwechselrichterschaltung, die sich insbesondere für den Betrieb von Leuchtstofflampen eignet und eine sinusförmige Wechselspannung mit einer Frequenz in der Größenordnung von 20 kHz liefert. Zur Verringerung der Schaltverluste des bzw. der Transistoren, die durch Rückkopplung mit einer sinusförmigen Wechselspannung angesteuert werden, enthält der Steuerkreis des bzw. der Transistoren in Reihe zur Rückkopplungswicklung eine Gleichspannungsquelle, die für die Transistoren in Durchlaßrichtung gepolt ist und deren Spannung allein ausreicht, die Transistoren durchzuschalten. Die Gleichspannungsquelle wird von einem Kondensator (9) gebildet, der mit Hilfe einer Diode (7,8) aus der Rückkopplungswicklung (6) aufgeladen wird. Es ergibt sich ein recheckförmiger Basisstrom mit überlagertem Sinusverlauf der sehr kurze Schaltzeiten der Transistoren (4,5) und damit geringe Verluste bewirkt.

摘要： This application provides a grid-connected photovoltaic inverter and a grid-connected control method. The photovoltaic inverter includes a control circuit and an inverter circuit. The control circuit is configured to: when a current value of the grid-connected point is greater than or equal to a current amplitude limiting value, obtain an active voltage adjustment amount and/or a reactive voltage adjustment amount based on the current value of the grid-connected point, the current amplitude limiting value, and a voltage value of the grid-connected point, and control an output voltage of the inverter circuit to be a target voltage value based on the active voltage adjustment amount and/or the reactive voltage adjustment amount, to reduce the current value of the grid-connected point by reducing active power and/or reactive power output by the photovoltaic inverter. A voltage value of a target voltage is the target voltage value. According to an application scenario, current limiting may be separately performed on an active current and a reactive current at a grid-connected point in this application. This maintains system stability, and improves system security Response is quick, the control method is simple, and applicability is high.
