摘要： An inverter transformer includes: a frame-core shaped substantially square; a plurality of I-cores disposed inside and coupled to the frame-core so as to provide a predetermined leakage inductance; and a plurality of primary and secondary windings provided respectively around the I-cores. The I-cores are divided into first group cores located not adjacent to one another and second group cores located not adjacent to one another but adjacent respectively to the first group cores. Magnetic fluxes generated in the first group cores flow in the same direction, magnetic fluxes generated in the second group cores flow in the same direction that is opposite to the direction of the magnetic fluxes generated in the first group cores, and respective voltages induced at secondary windings provided respectively around the first and second group cores are polarized identical with each other.

摘要： In an electrodeless discharge lamp of the type including an ionizable medium within a sealed envelope capable of emitting radiant energy when subjected to a radio frequency field, an oscillator for generating an output signal at a given radio frequency, a Class D RF amplifier including first and second transistors responsive to the oscillator output signal, and an induction coil responsive to the output of the amplifier, the coil being positioned in close physical proximity to the medium in the envelope for coupling to the medium an electric field having a magnitude sufficient to initiate ionization of the medium and a magnetic field for maintaining the ionization, there is disclosed an improved transformer for driving the Class D amplifier which results in a significant decrease in power consumption. The oscillator output signal is connected to the primary winding of a transformer which includes a toroidal, magnetic core. The transistors of the RF amplifier are connected to secondary windings wound on the core. The core is split between the secondary windings to form a high reluctance path which isolates the secondary windings from each other and critically couples the primary winding and the secondary windings.

摘要： A continuous load high-power flyback converter includes a first transformer having a first primary winding, a first secondary winding, and a first auxiliary winding, and a second transformer having a second primary winding, a second secondary winding, and a second auxiliary winding. The first primary winding and the second primary winding are connected in parallel between a power source and a transistor. The first secondary winding and the second secondary winding are connected in series to a diode and form an output of the continuous load high-power flyback converter. A load is connected between the output and ground. The first auxiliary winding and the second auxiliary winding are connected in series, and used to generate a control signal for the transistor. Connecting the primary windings in parallel and the secondary windings in series reduces the reflected voltage on the transistor for a given output voltage.

摘要： A substrate includes primary side terminal holes into which the primary side terminals are inserted, secondary side terminal holes into which the secondary side terminals are inserted, and a slit disposed between the primary side terminal holes and the secondary side terminal holes. A transformer is mounted from the side of a mounting surface of the substrate. An insulating member is inserted into the slit from the side of a soldering surface of the substrate. The insulating member includes a protrusion portion that protrudes outside an area defined by virtual lines which are direct extension lines of the width of the slit to the side of the soldering surface. The protrusion portion is formed at a position more distant from the substrate than an end position of the shortest terminal of the primary side terminals and the secondary side terminals from the soldering surface of the substrate.

摘要： A fluid treatment apparatus is constructed from at least one electrochemical cell including a bipolar ion exchange membrane and having a single output orifice to deliver treated fluid. The apparatus may employ a power supply transformer featuring a magnetic dispersion bridge to regulate the magnetic flux to secondary coils, thereby limiting the current delivered to the load and protecting the apparatus from over-current damage. The cell includes a membrane assembly which incorporates both the inner and outer electrodes to provide repeatable assembly and service, as well as reliable performance. The apparatus will provide continuous fluid treatment when designed with at least two stages, each stage including at least one cell, in which one stage is treating influent solution and another stage is regenerating. A method to operate these apparatus includes the steps of deionizing influent solution without interruption, halting deionization water flow and removing power from the deionization cells, flushing the liquid between membrane layers to the drain outlet, initiating regeneration power, and initiating regeneration flow.

摘要： A power receiving system includes a first receiving coil, a second receiving coil, a receiving circuit, a switching circuit, and a shorting circuit. The first receiving coil is at a first location on the cart. The second receiving coil is at a second location different from the first location on the cart. The receiving circuit generates direct current (DC) power from the power received by the first receiving coil or the second receiving coil. The switching circuit connects one of the first and second receiving coils to the receiving circuit. The shorting circuit disables the other one of the first and second receiving coils.
