Embodiment Construction

[0034] Figure 1a It is the circuit diagram of the transformer of the first embodiment of the present invention. The transformer comprises three parallel columns 1, 2 and 3, which are magnetically connected by two yokes 9, 9'. The above structure can be formed by a commonly used magnetic core. The two secondary coils 5, 6 are electrically connected with a capacitor 7 to form a resonant circuit. The resonant circuit has two inductivities represented by the secondary coils, each of which is located on a different cylinder. An air gap 8 is formed between the magnetic connection between the cylinders 2 , 3 wound around the secondary coils 5 , 6 . The main coil 4 is wound on the cylinder 1, and the secondary coils 5, 6 are wound on the cylinders 2, 3 respectively. Cylinder 2 or 3 serves as the center of the magnetic core.

Abstract

The invention relates to a transformer including a first (1), a second (2) and a third (3) leg which are aligned in parallel and are magnetically connected, having at least a first primary winding (4) and at least two secondary windings (5, 6). Each of the windings are carried by a different leg, whereby the legs are arranged in a sequence and one of the secondary windings is located between the other two legs. The two legs are connected with a capacity (7) and thus form a resonance circuit. The magnetic connection between the two secondary windings differs from the magnetic connections between the primary and each of the secondary connections. The flux excited by the first secondary winding is anti-parallel to the flux excited by produced by the second secondary winding. A supply voltage can be supplied at the primary winding and the transformer provides a current and a voltage at the secondary windings.

Description

technical field [0001] The invention relates to a power supply device, in particular to a transformer which can provide stable voltage. Background technique [0002] The power supply equipment is used to provide a stable voltage different from the line voltage, such as 110V or 230V, to the electrical equipment. The basic unit in power supply equipment is a transformer that converts an input voltage to an output voltage. The multiple relationship between the output voltage and the input voltage of the traditional transformer is fixed, and the multiple relationship is determined by the number of turns of the main coil and the number of turns of the secondary coil electromagnetically coupled with the main coil. When the current on the secondary coil increases, the voltage across the load connected to the secondary coil decreases. In addition, the secondary coil generally includes a resistor. [0003] Applied in the field of welding, conventional power sources exhibit the eff...
