تصميم دوائر الالكترونية المرحلة الثالثة .م.م. احمد عدنان المظفر Example 19: The range of spread of gate-cathode characteristics for a certain thyristor can be linearized to between 15V/A and 10V/A. The manufacturer's data gives the maximum gate. power dissipation as 5W. Sketch the characteristic up to Vcc = 15V G www R₁ 1:0 R₂ and I, 1.5A, and insert the PG(max av) line. With the gate firing circuit as shown in Fig. aside, a 1:1 isolating transformer, Vp amplitude of 20V, and R₁ = R2 = 202, determine the possible range of VGC and IG.
