Why should we increase the invert switching frequency?
The most effect of high invert frequency:
1. With the increase of the invert switching frequency, the volume and weight of the inverter are also reduced, and the power density is greatly improved, which can effectively reduce the storage, transportation, installation, operation and maintenance costs .
2. Higher invert switching frequency can get better dynamic response and stronger Grid adaptability .
3. Cooperate with Renac Power’s unique invert control algorithm and dead zone compensation technology to achieve very small harmonic distortion of output current.
1. Under the same conditions, selecting the appropriate switching component and increasing the invert switching frequency can reduce the system ripple voltage and ripple current, the AC loss is smaller , and the efficiency is higher.
2. Equivalently, increasing the invert switching frequency under the same conditions can reduce the capacitance and Inductor volume.
1. The detailed knowledge:
Increase the invert frequency under the same conditions and reduce the capacitor ripple voltage.
Increase the invert frequency in the same proportion and reduce the capacitance of the capacitor to obtain the ripple voltage of the same amplitude.
The same is true for inductor:
Under the same conditions, increasing the invert frequency, reducing the ripple current.
Equally increasing the invert frequency and reducing the inductance value can obtain the same amplitude ripple current, and the high frequency can be stabilized faster.
