Abstract
The invention provides an intermediate frequency static conversion power supply controller of an autosyn. The controller comprises a rectifier circuit, an inverter circuit, a filter circuit, a drive and an overvoltage and overcurrent protection circuit. According to the design, a main circuit adopts an alternating current-direct current-alternating current working mode, and is comprises the rectifier circuit, the inverter circuit, a transformer and the filter circuit; the main circuit enables power frequency current to pass through the rectifier circuit to obtain direct current; 400Hz sinusoidal alternating current is obtained through the inverter circuit; required voltage is obtained through the transformer; and finally harmonics are filtered out through the filter circuit to obtain an ultimate 400Hz intermediate frequency static conversion power supply required by the 28ZK4B type autosyn.
Description
Technical field
the present invention relates to a kind of selsyn medium frequency solid power supply controller, especially load is the 400Hz medium frequency solid power supply controller of 28ZK4B type selsyn.
Background technology
selsyn is widely used in naval vessels, airborne equipment and industrial control equipment.The performance of selsyn medium frequency solid power supply determines certainty of measurement and the service behaviour of the selsyn of system.The control of early stage selsyn medium frequency solid power supply is that analog circuit has come, but due to the drift of analog circuit and unsteadiness, the degree of regulation of output voltage and stability is restricted.Traditional 400Hz intermediate frequency power supply provides with rotary-type Current transform unit, and this rotary convertor is made up of Diesel engine and the 400Hz engine coaxial with it.Because diesel engine has heaviness, volume greatly, rough running, noise are large, because some component requirements precision is high, cause the shortcoming that cost is high.The visual field of people walked out gradually by now traditional rotary-type convertor.The substitute is the emergence of novel electric power electric equipment-inverter.
medium frequency solid power supply is the product of the electronic power switch converter technique adopting high frequency, and intermediate frequency refers to 400Hz in the present invention.Because medium frequency solid power supply has the features such as noise is little, precision is high, volume is little, waveform is outstanding, be now widely used in radar, naval vessels and industrial equipment.From present domestic and international research situation, many famous enterprises of foreign country such as Toshiba, Delta etc. have very significant achievement in quiet variable power source.These enterprises of foreign country are studied much in quiet variable power source, and a lot of technology is in the stage of ripeness, have manyly applied in the middle of reality.The quiet variable power source that their are produced can from a few hectovolt to several kilovolts, and service behaviour is more outstanding, and the advanced country such as American-European instead of traditional Current transform unit with quiet variable power source now.Comparatively speaking, domestic research starting in quiet variable power source is more late than foreign country a lot, and current most of domestic production producer is mainly based on the control mode of modulus, and the research of digital aspect is fewer.
Summary of the invention
the object of the present invention is to provide a kind of selsyn medium frequency solid power supply controller.The present invention is by obtaining direct current by power frequency electric by rectification circuit, the sinusoidal ac of 400Hz is obtained through inverter circuit, obtain required voltage through transformer, obtain the 400Hz medium frequency solid power supply required for final 28ZK4B type selsyn finally by filter circuit elimination harmonic wave.
the object of the present invention is achieved like this: the present invention is made up of rectification circuit, inverter circuit, filter circuit, drive circuit and over-voltage over-current protection circuit.Acp chip adopts XE164FN, as system controller, utilizes power MOSFET invention bridge inverter main circuit; By input voltage and the circuit of inverter circuit, invention rectification circuit, exchanges point and is converted to the use of DC rectification circuit by 220V, 50Hz; Utilize IR2110 as driving chip, carry out 28ZK4B type selsyn medium frequency solid power supply drive circuit; Form by analyzing harmonic wave, the output filter circuit of invention power supply, with elimination secondary and above harmonic wave thereof; Overvoltage crowbar causes permanent damage to prevent overvoltage to hardware circuit.
beneficial effect of the present invention: the present invention is directed to selsyn medium frequency solid power supply, controller of the present invention can prevent the short circuit of power supply, overvoltage etc. from causing permanent injury to device, provides selsyn medium frequency solid power supply safety and reliability.
