Embodiment Construction

[0014] refer to figure 1 , which is a functional block diagram of the power supply structure of the present invention.

[0015] According to the block diagram of this product, the AC alternating current is input into the power frequency transformer 1 and the power frequency transformer 2 respectively, and the output of the power frequency transformer 1 is rectified, filtered and stabilized to directly output 1 to 6 direct currents, and the rectified and filtered seventh road is converted by the panel. And after the adjustable control, the output is stabilized, and at the same time, the power frequency transformer 1 directly steps down and outputs the 8th AC. After the output of the power frequency transformer 2, it directly outputs 9 to 14 channels of DC through rectification, filtering and voltage stabilization. The 15th channel of rectification and filtering is subject to panel conversion and adjustable control and then output through regulated voltage. At the same time, the...

Abstract

The present invention provides a linear electric power source which outputs low ripple voltage and is used for audio equipment and other equipment that has low requirement to the output ripple voltage, wherein, the linear electric power source comprises an industrial frequency transformer, a commutating wave filtering circuit, a voltage regulator circuit, an output circuit, a panel indicating board and a voltage converting switch. The signal of the power supply circuit is inputted from AC and is transferred through the industrial frequency transformer and the commutating wave filtering circuit, is transferred through the voltage stabilizer to the output circuit, and at the same time is sampled to the panel for indicating; wherein two circuits directly output AC alternating current after the voltage releasing of the industrial frequency transformer. The linear electric power source adopts two annular industrial frequency transformers which are fixed on the casing by screws, and the structure of the electric power source is compact. The linear electric power source adopts one part of paster and is a novel-designed linear electric power source.

Description

technical field [0001] The invention relates to a linear power supply with very low output ripple voltage, belonging to the technical field of power supplies. Background technique [0002] Power supply is an essential part of all kinds of electrical products. Generally, it is configured in the equipment as a part of the product, or it is made into a single independent product. The power supply described here is a power supply used in audio equipment and other equipment that requires little output ripple voltage. [0003] In terms of circuit structure, the above-mentioned power supply is basically the same as other power supply circuits, that is, power frequency transformer, rectification and filtering, voltage stabilization, and output. The power supply products originally designed and produced by Shanghai Sanji Electronic Industry Co., Ltd. basically belong to this type of product. [0004] At present, the existing power supply generally only has a single power frequency ...
