High-Frequency Inverter: How They Work and Why
High-frequency inverters are available in various power sizes that can be customized according to usage requirements. Below is a
Frequency inverter relies on the internal IGBT to adjust the voltage and frequency of the output power supply, according to the actual needs of the motor to provide the required power supply voltage, and then achieve the purpose of energy saving and speed regulation.
The large majority of inverters available in the retail market are high frequency. They are typically less expensive, have smaller footprints, and have a lower tolerance for industrial loads. HF inverters have over twice the number of components and use multiple, smaller transformers.
Higher switching frequencies generate more heat, requiring more robust cooling solutions. Efficiency Considerations: The efficiency of the motor and inverter system is affected by the switching frequency. While higher frequencies can reduce certain losses (like torque ripple), they increase others (like switching losses).
Size and tolerances of the transistors used in the inversion process, and the speed at which they operate determines the classification of high or low frequency. The large majority of inverters available in the retail market are high frequency.
