Grid Tie Three Phase Voltage PWM converters can be conceived as current sources that inject currents into the grid at the point of common coupling (PCC). In order to achieve a good performance, the voltage source inverter (VSI) should be commanded by a current controller to track as accurate...
三相异步电动机转速公式(Three-phase asynchronous motor speed formula) Three-phase asynchronous motor speed formula The speed formula of three-phase asynchronous motor is: n = 60f/p (1-s) From the above, it can be seen that changing the power supply frequency f, the extreme logarithm of the...

The phase voltage equation for an SRM is vph=Rsiph+dλph(iph,θph)dt where: vph is the voltage per phase. Rs is the stator resistance per phase. iph is the current per phase. λph is the flux linkage per phase. θph is the angle per phase. Rewriting the phase voltage equation ...
In order to maintain the main magnetic flux Φ constant, while changing the power frequency f1, it is also necessary to change the power voltage U1 and keep the U1/f1 ratio constant. This is the characteristic of variable frequency speed regulation. ...

The present invention provides a three-phase voltage source inverter system capable of obtaining a nearly sinusoidal output waveform while minimizing apparatus size increase and cos
installations. Components such asprotection devices, distribution boards and transformers are also built differently. In the case of transformers, you can use three single-phase units to step a three-phase voltage up or down, but a three-phase transformer is less expensive and more compact in ...
