Abstract
The integrated inverter power supply consists of power step change, control circuit, filter circuit and output electrode. When a DC voltage is input, the control circuit controls the two field effect driving tubes NM1、NM2And conducting the work in turn, and filtering and shaping the work to output the required frequency voltage value. The discrete components are connected and installed in a metal shell in a three-dimensional arrangement mode, input and output leads are connected to corresponding end points, and the integrated device is packaged by using a filler and an insulating material. The device has small volume, no interference of an external circuit, no noise and large output power.
Description
The utility model relates to a kind of stabilized voltage power supply device, particularly contravariant power device.
Conventional inversion formula power supply apparatus is that discrete component is assembled on the circuit board and the instrument and equipment adapted, and it is big to take volume after the assembling, the exposed gas attack that is subjected to of element, grey, oily dust pollution and vibration effect, reduced device useful life, it is big also to have a noise, need set up shortcomings such as heat abstractor.
The purpose of this utility model is the contravariant power circuit of a kind of advantages of simple of design, and will be separately independently components and parts be assembled into an integral device, make its interference that is not subjected to outside air and operational environment, noiseless, volume are little, need not attached heat sinks.
The utility model is imported a direct current voltage, by two field effect driving tube NM of control circuit control

The utility model is compared with contravariant power device in the past has following advantage:
1, because the integration of device, dwindled volume greatly, be convenient to various instrument and equipment adapteds, shell double as radiator, attached heat sinks and other annex have been removed, only needing input one direct current voltage, be convenient to finish the repertoire of inverter, can be the voltage output of 50HZ 220V or 400HZ 115V with direct voltage 24V or 27V inversion.
2, owing to adopt integrated packaging, this device is not disturbed by external circuit, avoids the influence of corrosive gas, air humidity and vibration, noiseless, and power output is big, stable performance.
