  1. CO2 Laser (The molecular gas laser)

    CO2 Laser (The molecular gas laser) The CO 2 stands for carbon dioxide. In CO 2 laser the laser light takes place within the molecules … the type of molecular gas laser. Importantly note that CO 2 lasers use carbon dioxide as well as …

  2. Torque

    … this force in one revolution = Force x distance = F x 2 Δr Jouls Let N = revolution per seconds. P = Power developed. Power developed = F x 2 Δ rN Joules/second. P = Fxrx2 Δ N P = T x 2 … can write: T = K 1 Ø I 2 Cos Ø2 where K 1 = another constant. STARTING TORQUE (Ts) The torque …

  3. SCR In Parallel

    … to increase their common current capability. If SCRs are not perfectly matched, this results in an unequal sharing of … V-I characteristics of two SCRs, SCR 1 and SCR 2 . The ratings of the SCRs are the same. When these SCRs … extra power loss in the resistor. Moreover, resistors do not compensate for unequal SCR turn ON or turn OFF times. …

  4. Half Wave Rectifier One Plus Rectifier

    … with respect to the cathode and the diode turns off. Then no current flows through R. The output voltage ( V O ) … = I m / π --------------------------------eq. 2 = 0.318 I m Where I m = V m / R … into DC power. Since we are assuming ideal devices, with no power has in the rectifier, the net power flow at the AC …

  5. SCR in Series

    … forward-blocking capability. However, it's important to note that the characteristics of two SCRs, even those of the … SCR2 ( V 1 ) is higher than that across SCR 2 ( V 2 ) because the leakage current for SCR 1 is smaller …

  6. Voltage Multipliers
