College of Electrical Engineering, Southwest Jiaotong University Courseware Download (for postgraduate examination may be helpful) [size=2][color=purple] circuit analysis of Southwest Jiaotong (last code 426, this year code 922) because today, a new Tan Yongxia teacher's < circuit analysis > (05 Sichuan Provincial fine Course), you may be a little nervous, in fact, as long as the circuit (Chu Guanyuan) book every chapter to understand, there is no problem.
Specifically, combined with his own last year's Test experience (circuit Analysis 143 last year), the focus of the exam is generally these
(1) Equivalent transformation of power supply, analysis method of mutual inductance circuit (mainly decoupling)
(2) The Nodal voltage method solves the circuit, in which the reference node's selection general question is given, the examination is nothing but the current source and the resistor series branch's column writes the equation, as well as in the node exists the current source problem.
(3) Thevenin theorem and reciprocity theorem, in which the Thevenin theorem focuses on the external power supply method and open short-circuit method for solving the equivalent resistance, which also needs to know the essence of superposition principle.
(4) The R,l,c circuit's phasor representation, the key is the Phasor circuit diagram
(5) First-order circuit three elements, initial value, steady-state amount, time constant (understanding from capacitance or inductance to see the past equivalent resistance of the method), 0+ moment of transformation
(6) Z,y,t,h parameter and its strict reference direction, that is, the voltage and current direction of the two-port network, the sense T parameter and Z parameter are more
(7) An S-domain operational circuit, paying special attention to the initial value of the capacitance inductance at the time of t<0, and then the equivalent transformation needs to be considered strictly.
(8) Nonlinear resistor, how to decompose the non-linear part, the derivation regards the exchange as DC.
(9) Three-phase alternating current circuit, star shape, triangle transform, line current line voltage (pay special attention to the triangular connection of the electric line of the phase hysteresis phase current 30 degrees), as well as three-phase power.
(10) Equation of state [/color][/size]
