Inverter is similar to converter, some times some people mix them into one thing, in fact it is quite different.
Generally speaking, we name the steady voltage and frequency AC change to variable voltage or frequency of alternating current (ac) device called a "converter".
VVVF: change Voltage, Frequency, Variable Voltage and Variable Frequency).
CVCF: Constant Voltage and Constant Frequency (Constant Voltage and Constant Frequency).
In order to produce the variable voltage and frequency, frequency converter must first convert the power of the alternating current (AC) to direct current (DC), and then convert direct current (DC) to alternating current (AC). Frequency converter for motor control, can change the voltage, and can change the frequency. But most of the frequency converter used in fluorescent lamp is used to adjust the frequency of power supply.
Cars use alternating current generated by the cell (dc) of the equipment is in the name of "inverter" for sale. The working principle of the inverter is widely used in various fields.Take an example, the Power supply of computer switching power, in this application, frequency converter is used to inhibit the reverse voltage, frequency, power fluctuation and the short circuit.
