摘要： A variable frequency resonant converter (310,320;400) includes an inverter stage (402), a resonant circuit (404), a transformer (406), a rectifier stage (408), and a controller (250). The inverter and rectifier stages include first and second FET devices (410,412,420,422). The inverter converts a DC input signal to a first AC signal. The resonant circuit is coupled to the inverter stage and filters the first AC signal. The transformer is coupled to the resonant circuit and converts the first AC signal to a second AC signal. The rectifier stage is coupled to the transformer and converts the second AC signal to a DC output signal. The controller is configured to operate both of the first and second FET devices substantially at a resonant frequency at least partially defined by the resonant circuit to generate the DC output signal according to a voltage setpoint.

摘要： A method for controlling the switching of an inverter, a bridge of which is adapted to chop a voltage from a direct voltage source for feeding a chopped voltage to a primary of a transformer; the inverter comprises a diode rectifier circuit receiving the input voltage from the secondary of the transformer in order to achieve a voltage fed to a chopper which feeds a load. The method comprises: a step in which the switches of the bridge are driven so that the power source is disconnected from the primary, the terminals of which are connected to each other by at least two of the electronic switches and recirculation diodes of the bridge itself, so that the voltage present on the secondary of said transformer is null; a step in which the switching of at least one electronic switch of a chopper branch is achieved when the voltage on the secondary is substantially null in order to minimize switching losses due to the opening/closing of the electronic switch of the chopper.

摘要： The efficiency of an X-ray generator (80) is improved, the maintenance man-hour of an X-ray CT apparatus comprising the X-ray generator (80) is reduced, the reliability of the X-ray CT apparatus is improved, and the space where the X-ray CT apparatus is installed is decreased. The X-ray generator is composed of an AC power supply (1), a power transmitting means (8), an AC-DC converter (4), an inverter (5), a high-tension transformer (8), a rectifying means (9), and an X-ray tube (11). The X-ray generator is mounted in a scanner rotating unit (108) of the X-ray CT apparatus. The converter (4) is controlled by a converter control circuit (12) so that the phase of the phase voltage of the AC power supply may agree with the phase of the phase current and the output voltage may be equal to the desired voltage. The inverter (5) effects zero-voltage switching of a semiconductor switching element constituting the inverter when the switching element is turned on/off, circulates the current flowing through the zero-voltage switching means when the zero-voltage switching means is cut off, and controls the timing of the on/off of the inverter according to the voltage and current of the X-ray tube.

摘要： A converter has a resonant circuit with an auxiliary valve (18), an inductor (17) and capacitive means (15) for assisting in the commutation of the converter. A control device (24) is adapted to control turn-on and turn-off of gate turn-off semiconductor elements of current valves of the converter and controllable semiconductor devices of the auxiliary valve. Means are provided for measuring the current in a phase terminal (10) of the converter. Upon commutation of the phase current from a gate turn-off semiconductor element (13) of one current valve to a rectifier member (14) of another current valve, the auxiliary valve is turned on with a variable time lag after turn-off of the first valve. Means are provided to determine the magnitude of the time lag in dependence on the magnitude of the direction of the measured phase current.

摘要： In the parallel resonant DC link inverter described in the specification, a DC voltage is applied to a plurality of semiconductor switches to provide an AC driving voltage for an AC motor by way of an LC tank circuit containing a nonlinear capacitance device having an antiferroelectric material as its dielectric. As a result of the increase in capacitance with increased voltage, the voltage peak of the link voltages produced by the circuit is reduced without a corresponding reduction in the volt-second product applied to the motor load.

摘要： A boost rectifier is provided with an ultra high speed diode (D) in its direct current rail to reduce diode reverse recovery loss with or without implementing a soft switching technique. Full zero-voltage-transition (ZVT) as well as zero-current transition (ZCT) may also be achieved by adding a simple auxiliary network (Lr, Daux, Saux) across the DC rail which operates only during the short turn-on transients of the bridge switches (Sap-Scn). Similarly, a simple, inexpensive auxiliary circuit can be added to the DC rail of a conventional voltage source inverter shown to implement both ZVT and ZCT.
