Magnetic bearing soft switch three-level power amplifier

Abstract

The invention discloses a magnetic bearing soft switch three-level power amplifier, which comprises an amplifier main body, an adjustment knob, an electronic tube, a first input device, a first rubberpad, a wiring column, an anti-oxidation device, an end cover, a work chamber, a second input device, a precision electronic tube, a second rubber pad, a switch, a flexible tube, a buffer sleeve, a receiver, a damping mesh opening, a bottom plate, a fastening screw and a sponge layer. the first input device is arranged on one side of the top end of the amplifier main body; the electronic tube is arranged on one side of the first input device; the second input device is arranged at the other side of the electronic tube; the adjustment knob is arranged at one end of the amplifier main body; theswitch is arranged on one side of the adjustment knob; the first rubber pad is arranged at the side end of the amplifier main body; and the second rubber pad is arranged at the other side of the firstrubber pad. The noise of the power amplifier can be substantially absorbed and reduced through the cooperation of the sponge layer with the damping mesh opening, thereby reducing the potential risk of electromagnetism.

Description

Technical field: [0001] The invention relates to the field of power amplifiers, in particular to a soft-switching three-level power amplifier of a magnetic suspension bearing. Background technique: [0002] At the same time as human mechanical progress, the use of modern power electronics technology to achieve power amplification is currently the most commonly used method. As a key component commonly used in various power supplies and instruments, it usually requires a faster dynamic response speed and a smaller volume. High energy efficiency is required, while EMI interference should be small to prevent interference to surrounding products. However, the existing power amplifiers have large current ripples, so that the input device is usually accompanied by electromagnetic noise, which has certain potential dangers. When the parts are used for a long time, oxidation is prone to occur, which aggravates the plane wear of the parts, which is not conducive to The work and opera...
