Inverter comparison of the embodiments of the present invention:
(1) the high-frequency inverter adopts an inverter circuit boosted by a high-frequency transformer; firstly, inverting low-voltage direct current into high-frequency low-voltage alternating current by a high-frequency DC/DC conversion technology, boosting the voltage by a high-frequency transformer, and rectifying the voltage into high-voltage direct current generally more than 300V by a high-frequency rectifying and filtering circuit; and finally, obtaining 220V power frequency alternating current for load use through the power frequency inverter circuit. Because the high-frequency inverter adopts the high-frequency magnetic core material with small volume and light weight, the power density of the circuit is greatly improved, so that the no-load loss of the inverter power supply is small, and the inversion efficiency is high.
(2) The power frequency inverter is designed by the traditional analog circuit principle, and an inverter circuit boosted by a power frequency transformer is adopted inside the power frequency inverter. Firstly, inverting the direct current into power frequency low-voltage alternating current; and the alternating current is boosted into 220V50Hz alternating current for load use through a power frequency transformer. Its advantages are simple structure and low voltage for protecting various functions. Because the power frequency transformer is arranged between the inverter power supply and the load, the inverter has stable and reliable operation, strong overload capacity and impact resistance, and can inhibit higher harmonic components in the waveform.
Because the components (such as a transformer, an inductor and a capacitor) in the power frequency inverter are relatively large, the power frequency inverter has the problem of heaviness and relatively low efficiency. The rated load efficiency of the transformer is generally not more than 90%, and the iron loss of the power frequency transformer is basically unchanged when the power frequency transformer runs under full load and light load, so that the no-load loss of the power frequency transformer is large when the power frequency transformer runs under light load, and the efficiency is low; the comparative results are shown in Table 1.
TABLE 1 comparison of high frequency inverter to Power frequency inverter
| Efficiency of | Performance of | Volume/weight | |
| High frequency inverter | Height of | Can be carried at low power | Small size and light weight |
| Power frequency inverter | Is low in | Can carry with high power | Large volume and heavy weight |
No matter high frequency UPS or power frequency UPS load carrying ability is enough to ordinary domestic appliance (do not include heating equipment such as air conditioner electric heater), and domestic UPS requires more to aspects such as volume, cost, and high frequency inverter has efficient, and is small, light in weight's characteristics, suitable uses in domestic UPS.
Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can make modifications and equivalents to the embodiments of the present invention without departing from the spirit and scope of the present invention, which is set forth in the claims of the present application.
