Car inverter is a work in high-current, high-frequency environment power products, the potential failure rate is very high. Therefore, consumers must be careful when DC AC power inverters buying. First, from the inverter output waveform selected, preferably not less than quasi-sine wave; secondly, to have a complete circuit of the inverter protective function; Third, manufacturers have a good after-sales service commitment; fourth, circuits and products have been tested over time.
Inverter, inverter device must be composed of a thing to so called, the difference between him and the transformer directly, that is, he can achieve a DC input and output AC, working principle and switching power supplies the same, but the oscillation frequency in within a certain range, for example, if the frequency is 50HZ, output was AC 50HZ. The inverter frequency can be changed in the device.
Transformers generally refers to a device-specific frequency bands, such as frequency transformer, the transformer is that we usually see, they both inputs and outputs solar power inverter must be within a certain range, for example, can work within the 40-60HZ range.
