摘要： Disclosed are a method and a device for cooling a high voltage transformer for a microwave oven, in which the high voltage transformer is sealed so as to separate a coil and a core from the outside and to improve a cooling effect, and in which electric connection lines leading from the high voltage transformer are effectively treated and a fixed structure of a container for accommodating the high voltage transformer is improved so as to protect users of the high voltage transformer from dangers such as an electrical shock occurring in inspecting the microwave oven, thereby improving performance and quality of the microwave oven and the high voltage transformer. The method for cooling the high voltage transformer for the microwave oven comprises the steps of: inserting the high voltage transformer into a container with a designated size and sealing the container; injecting a cooling oil into the container so as to absorb heat of a high temperature generated from a coil and a core of the high voltage transformer; and cooling the cooling oil absorbing the heat by radiating the heat via the container exchanging the heat with the outside.

摘要： A discharge lamp illumination circuit 1 has a DC-AC conversion circuit 3 which effects AC conversion and boosting upon receipt of a DC input, and a starter circuit 4 for supplying a start-up signal to a discharge lamp. Power output from the DC-AC conversion circuit 3 is controlled by control means 6, thereby controlling illumination of a discharge lamp 10. An AC transformer 7 constituting the DC-AC conversion circuit 3 is provided, and a primary circuit and a secondary circuit, both forming part of the AC transformer 7, are insulated from each other. The start-up signal boosted by the AC transformer 7 is superposed on the AC-converted output, and the resultant signal is supplied to the discharge lamp 10. Thus, the need for a starter transformer specifically designed for startup can be obviated.

摘要： A transformer, particularly for a voltage converter, has a primary winding having a predeterminable leakage inductance and at least one secondary winding magnetically coupled to the primary winding with a predetermined voltage-transformation ratio. The (primary) leakage inductance is increased as compared with a conventional transformer without violating the limits for implementing an appropriately functioning transformer, and without choosing an additional coil or a larger core than is required for the power transformation, in that the primary winding comprises at least two winding sections whose magnetic couplings to the at least one secondary winding are implemented such that they operate in mutually opposite senses and are arranged such that they are at least substantially magnetically decoupled from one another.

摘要： A method and apparatus to amplify the magnetic field in an electromagnetic circuit is provided. Amplification factors of several orders of magnitude may be obtained. The system is applicable to a number of different systems, including melt levitation and electromagnetic pumping and propulsion. One embodiment of the invention uses a non-conducting permeable core wound around a dielectric core. An alternating voltage source is connected to a solenoid which is wound around a section of the permeable core. The permeable core has a gap within which a flux concentrating cold crucible is provided. Melt levitation processing takes place within the cold crucible. A fluid redirection skirt having an intake port partially surrounds the gap and conducts fluid through an exhaust nozzle.

摘要： In a converter which is usable as a kind of DC--DC converter and which comprises a transformer for processing an exciting current into an excited current under influence of an inductance value of the transformer, the inductance value is controlled in compliance with a value of the exciting current. The exciting current is controlled by a current control circuit with reference to the excited current so that exciting current is intermittently supplied to the transformer. While the exciting current is absent during intermittent supply to the transformer, the transformer produces the excited current.

摘要： A discharge lamp ballast for stabilizing wattage input into a discharge lamp at different levels in two or more ranges comprises a magnetic core forming a closed magnetic circuit. A main winding on the core may be used alone or with an extended winding switched in series, and be connected in series with the lamp across an alternating current source in a lamp operating circuit. A control winding on the core has a triac connected across it to vary the current and thereby the wattage supplied to the lamp in the operating circuit. A pair of gapped shunts, one located between the control winding and the extended winding, and the other between the extended winding and the main winding, assure a proportionally greater control effect on the series reactance in the lamp operating circuit when the extended winding is switched in than when it is not.
