Description
Technical field:
The utility model relates to a kind of energy-efficient frequency conversion generator.
Background technology:
General traditional sine wave generator generating efficiency is low, and the copper cash consumptive material is big.
Summary of the invention:
The purpose of this utility model is to provide the energy-efficient frequency conversion generator of a kind of generating efficiency height, consumptive material province.
The technical solution of the utility model is as follows: it is at the power output end that has ultrasonic-frequency rotory generator now current rectifying and wave filtering circuit and dc inversion circuit to be set, current rectifying and wave filtering circuit is connected with the power output end of ultrasonic-frequency rotory generator, and the dc inversion circuit is connected with current rectifying and wave filtering circuit.
The utility model is compared with existing generator and is had the following advantages: (1) efficient height, the efficient of the energy-efficient frequency conversion generator of the utility model can reach more than 98%, because the frequency of traditional generator is 50Hz, if it is become direct current, by halfwave rectifier, can only rectification go out 50 positive poles in DC power supply each second, and the frequency of energy-efficient frequency conversion generator can be about 500Hz, and rectifiable each second of so energy-efficient frequency conversion generator goes out 500 positive poles in DC power supply.Therefore energy-efficient frequency conversion generator of the present utility model is compared with the generator of power with tradition, because the frequency of energy-efficient frequency conversion generator exceeds about ten times of the conventional electric generators frequency, therefore, the magnetic conduction ability of silicon steel sheet has improved greatly, magnetic resistance is corresponding also to have diminished, magnetic loss is also little, so the efficient of generator has improved greatly, efficient can reach more than 98%.(2) consumptive material is economized, and general traditional 50Hz sine wave generator is such as using sectional area 1mm
2The copper cash coiling, and energy-efficient frequency conversion generator with situation with the conventional electric generators of power under, only need 0.1mm
2The copper cash coiling, reactive loss is few, so materials are also economized, copper product can be saved ten times and get off.The for example remote electricity of carrying will be raised to original supply voltage hundred times even thousands of times of conveyings, and loss is very little in course of conveying like this, so also become the efficient energy-saving product.The utility model is a kind of reliable and stable safe a kind of new power supply.
Description of drawings:
Fig. 1 is the schematic diagram of high efficiency generator.
Fig. 2 is the schematic diagram that is connected the current rectifying and wave filtering circuit of the energy-efficient frequency conversion generator output of the utility model.
Fig. 3 is the inverter circuit schematic diagram that is connected rectification filter circuit output end of the present utility model.
Embodiment:
As shown in Figure 1, 2, the utility model is with the direct current of high-frequency current after over commutation and filtering of ultrasonic-frequency rotory generator output, passes through inversion again, becomes the AC power source of sine wave of 220V50 week (or 60Hz), supplies with various electrical works then.As shown in Figure 2, described current rectifying and wave filtering circuit is existing current rectifying and wave filtering circuit.As shown in Figure 2, described inverter circuit is to be made of isolated gate FET T1, T2, T3, T4 and resistance R, and T1 and T2 are connected in series, and T3 and T4 also are connected in series, one end of resistance R is connected on the line between T1 and the T2, and the other end of resistance R is connected on the line between T3 and the T4; When the T1-T4 conducting, T2 and not conducting of T3, electric current is flowed through resistance R to T4 by T1; When the T2-T3 conducting, T1 and not conducting of T4, electric current is flowed through resistance R to T3 by T2; Thus, at (being G, H end) the output 50Hz at resistance R two ends or the AC sine wave of 60Hz, 220V.
