Background technology
Along with the continuous development of power consumption equipment and advancing by leaps and bounds of science and technology, also more and more higher to the specification requirement of electric supply installation.In known technology, the inverter that existing direct current is transformed into alternating current mainly is the two-tube half-bridge driven that adopts, constitute with full-bridge type DC power supply circuit, limit by its structure, the alternating current that the every output of inverter is 1 hertz, DC power supply need provide forward current and reverse current respectively once, just can finish the alternation process, its structure is complicated, inefficiency, and when output AC power source side voltage than sinking during to critical value, load will be charged to direct current intermediate link, thereby increased the reactive power of inverter output, inverter autophage energy height.
Summary of the invention
In order to overcome the deficiencies in the prior art, solve the problem that the existing inverter structure is complicated, consumed energy is high.The purpose of the utility model provides a kind of simple in structure, stable performance, and consumes power is low, and adjustable frequency is wide, and the configuration of direct current and transformer is easy, new-type inverter applied widely.
The technical scheme in the invention for solving the above technical problem is:
A kind of novel inverter, it is provided with: battery pack DC, mains switch K, inverter ic 1-2, field effect transistor T, capacitor C 1-2, resistance R 1-3 and transformer B, the primary coil L1-2 of series transformer B behind the positive terminal connection mains switch K of battery pack DC, connect battery pack DC negative pole behind the primary coil L2 series capacitance C1 of transformer B, field effect transistor T shunt capacitance C1 forms switching circuit, inverter ic 1-2 connects resistance R 2-3 respectively, capacitor C 2 is formed non-steady-state oscillation circuit, connect field effect transistor T behind the non-steady-state oscillation circuit series resistance R1 and form control circuit, the secondary coil L3-4 of transformer B is the alternating current output line.
Above-mentioned novel inverter, described battery pack DC connects the solar DC battery pack.
Above-mentioned novel inverter, the inverter ic 1-2 of described oscillating circuit are CMOS type 4049,40106,4,093 six inverter buffer or four inverters, or other suitable type integrated circuit.
The utility model is the principle according to the electromagnetism interaction, the primary coil that utilizes field effect transistor to pass through transformer is formed switching circuit, conducting state produces directional magnetic field, off state produces the opposing magnetic field, electric weight when battery pack just consumes the field effect transistor conducting state, output AC in the secondary coil of transformer.Above technical scheme is magnetic field and the electric field that has made full use of transformer, realizes the function of novel inverter.
When the utility model uses, install desired location according to actual needs, DC provides direct current energy by battery pack, after the power-on K switch, oscillating circuit is in no steady operation state, field effect transistor one open-one close discontinuous operation, the polarity of the magnetic field of transformer will reverse continuously, the alternation electric weight output of magnetic field energy driving transformer secondary coil.
Because technique scheme has been adopted in the utility model design, has solved the problem that the existing inverter structure is complicated, consumed energy is high effectively.Also show through test for several times is on probation, it compared with prior art, have simple and practical, stable performance, consumes power is low, adjustable frequency is wide, advantages such as the configuration of direct current and transformer is easy, and is applied widely are applicable to the power consumption equipment power supply that is become alternating current by direct current for various, also can expand to the high power contravariant device of single-phase or three-phase alternating current by parallel connection or series system.
