So, the angles (50˚ and 230˚) is the point in time where we have applied the gate pulse, and the Thyristor starts conducting this is known as the Triggering angle of the SCR. The angles (180˚ and 360˚) where the Thyristors stops conducting and got turned off, called the Co...

A recurrent approach to calculate the attenuated inrush current is derived based on the transformer equivalent circuit. Formulas to calculate the dependence of dead angle and inrush current amplitude on time are presented by curve fitting. That provides a useful tool for the analysis and calculation...
Power (single phase):P=Vp×Ip×cosφPower (3 phases):P= √3Vl×Il×cosφorP= √3Vp×Ip×cosφ Power factorPF= cosφ=R/(R2 + X2)1/2,φ= power factor angle. For the purely resistive circuit,PF= 1 (perfect). The apparent powerSis calculated according to Pythagoras, the active ...
One can see that all of them are independent of polar angle φ and only 2p state angular wave function depends on azimuthal angle θ . Finally, there are found the semi-classical electron atomic orbitals ψ i ( r → ) for boron atom: ψ 1 ( r → ) = 1 π ( Z 1 r B ) 3 ex...
The basic circuit theory and power balance theory could be satisfied over the whole network. In this study, a method is developed to solve the above problem. The method is based on a converged AC load flow with several matrix formulations, where all electrical components can be solved and ...
