Embodiment Construction

[0015] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0016] figure 1 The structure of the high-efficiency and low-loss high-frequency power supply provided by the present invention is shown. It includes drive unit 1 and control unit 2. The input signal is driven by the drive unit 1 to drive the high-power tube to work, the signal is controlled by the control unit 2, and then the signal is output.

[0017] The driving unit is used to transmit the input to the unit under test, drive the unit under test to execute, accept the execution result of the unit under test, and make a judgment. A medium-power switching tube is used, and the output is driven ...

Abstract

The invention discloses a high frequency power supply with high efficiency and low loss. After passing through a resistor R1, an audion Q1 and an audion Q2, an input signal reaches a field effect tube M1 through a resistor R111 and outputs a signal through a resistor R100; a voltage-regulator tube D1 enables the field effect tube to work at a certain voltage. A high power tube works at an open zone and a close zone after being driven by a power amplifying tube, and then connected to a AT89S2051 singlechip pin P1.0-P1.5 of a control unit; through the action of a singlechip, the output current is effectively controlled, and the purposes of preventing a molybdenum wire from burning and breaking for excessive current and reducing loss of the molybdenum wire are achieved. Through the principle, the effect of debugging the software write on a machine tool is very good, the normal processing efficiency is up to more than 8,000 per hour, and also 12,000 per hour as the fastest. The loss of the molybdenum wire is one time higher than that in the past, so that the problems of low processing efficiency and high molybdenum wire loss of the quick thread cutting high-frequency power are solved effectively, the loss of each company is reduced; the high efficiency and high-benefit operation of every company is guaranteed; therefore, the high frequency power supply has a very good effect.

Description

technical field [0001] The invention belongs to the technical field of power supplies, in particular to a high-efficiency and low-loss high-frequency power supply. Background technique [0002] At present, the high-frequency power supply for fast wire cutting is widely used in various mechanical processing. However, due to low processing efficiency and large loss of molybdenum wire, many losses have been caused. Contents of the invention [0003] The purpose of the embodiments of the present invention is to provide a high-efficiency and low-loss high-frequency power supply, which aims to solve the problems that the high-frequency power supply for fast wire cutting is widely used in various mechanical processing, but due to low processing efficiency and large loss of molybdenum wire, etc. , causing a lot of loss problems. [0004] The implementation of the present invention is achieved in this way, a high-efficiency low-loss high-frequency power supply, characterized in th...
