摘要： A DC power source voltage is supplied to a center tap of a primary winding, and first and second semiconductor switches alternately turned on are disposed between each of both ends of the primary winding and a common potential point, and a current flowing through a load is fed back and PWM control of each of the semiconductor switches is performed. Also, snubber circuits are respectively connected between a ground and the center tap of the primary winding, and an abnormal high voltage at the time of switching is reduced. Also, a parallel running of plural inverters is simply performed by disposing PWM comparators corresponding to the first and second semiconductor switches.

摘要： In a two stage inverter providing power to a load, a first stage component is operable to receive a first voltage input and a first control input to generate a first voltage output, which is higher than the first voltage input. The first control input is indicative of the power provided to the load. The first voltage output varies in response to a change in the first voltage input by a predefined function. A second stage component of the inverter is operable to receive the first voltage output and a second control input to generate the power as an output. The second control input is indicative of the power provided to the load. A controller component of the inverter is operable to receive a feedback input indicative of the power required by the load and generates the first and second control inputs.

摘要： A phase locked loop (PLL) circuit provides ac devices, such as power inverters and power measurement devices, with a reliable means for synchronizing to ac electrical systems. In an exemplary embodiment, the PLL circuit is configured for operation with single-phase electrical systems and offers substantial noise immunity by basing its locking operations on measured fundamental components, i.e., measured x-y phasors, of the electrical system voltage. Further, with its phasor-based locking operations and with its timer/counter-based operation, the PLL circuit can be implemented partly or wholly in digital processing logic.

摘要： An integrated circuit inverter controller that includes at least one input pin that is configured to receive two or more input signals. The input pin may be multiplexed so that the appropriate input signal is directed to appropriate circuitry within the controller to support two or more functions of the controller. Alternatively, the input signals may be present in differing time periods so that a single pin can support two or more functions. Multifunctional or multitasked pins reduce the overall pin count of the inverter controller.

摘要： A power supply for a quadrupole mass spectrometer which operates using an RF signal. The RF signal is controllable via a feedback loop. The feedback loop is from the output, through a comparator, and compared to a digital signal. An air core transformer is used to minimize the weight. The air core transformer is driven via two out of phase sawtooth signals which drive opposite ends of the transformer.

摘要： A circuit arrangement for the square-wave modulated high-frequency voltage operation of a discharge lamp, including means to control the duty cycle of the square wave, has a measuring circuit for detecting the ignition of the discharge lamp during each cycle of the substantially square-wave modulation and a timer circuit coupled to the measuring circuit for rendering the amplitude of the high-frequency voltage substantially equal to zero when a time interval has elapsed after the ignition of the discharge lamp, whereby the luminous flux of the discharge lamp fluctuates to a low degree only.
