Built-in voltage of pn junction formula

WebThe knee point voltage of ct can be calculated using the following formula. Vkp = K * If/CTR x (RCT + RL + RR) Where, K = Constant, usually taken as 2.0 Vkp = The least Knee Point Voltage If = Utmost fault current at the position in Amperes CTR = CT Ratio RCT = Secondary winding resistance of CT in Ohms RL = Two-way lead resistance in Ohms Webwhere Vbi is the built-in voltage of the junction and VF is the externally applied forward bias. If the junction is subjected to reverse bias, VF should be replaced with -VR, therefore equation (17) becomes: ∫ SCR xρ x ε dx=Vbi +VR (18) In the case of homogenous semiconductor junctions, this formula can be written as: 1 ε ∫ SCR xρ x dx ...
