Frequency converter common sense
The frequency converter is a power control device that converts the power frequency power source into another frequency by utilizing the on-off effect of the power semiconductor device. There are various classification methods of frequency converters. According to the main circuit operation mode, they can be divided into voltage type inverters and current type inverters. According to the switch mode classification, they can be divided into PAM control inverters, PWM control inverters and high carrier frequencies. PWM control inverter; according to the operating principle classification, can be divided into V / f control inverter, slip frequency control inverter and vector control inverter; according to the classification of use, can be divided into general inverter, high-performance dedicated inverter, High frequency inverter, single phase inverter and three phase inverter.
