2.验证输出电压E2与tc/to、n2/n1和E1的关系将前述参数代入E2=(tc/to)×(n2/n1)×E1,可得E2的理论值为110.4V。仿真进入平稳状态后,输出端电压表的读数为108.2V。仿真结果与理论计算基本相同。顺便指出,由高等教育出版社出版,李伟辉主编的中等职业学校电子电器专业国家教委规划教材《电视机原理(下册)》第43页中,描述输出与输入电压关系的两个式子(4—1)和(4—2)不正确,阅读该书时 2. Verify the relationship between output voltage E2 and tc / to, n2 / n1 and E1 Substituting the above parameters into E2 = (tc / to) × (n2 / n1) × E1, the theoretical value of E2 is 110.4V. After the simulation into a steady state, the output voltmeter reading 108.2V. Simulation results and theoretical calculations are basically the same. By the way, the two formulas (4) describing the relationship between the output voltage and the input voltage are described in “Principles of Television Sets (Volume II)”, “The Principles of Television Sets,” published by Higher Education Press and edited by Li Weihui -1) and (4-2) are incorrect, when reading the book
