在宽频带变压器中,漏电感和分布电容是影响高频性能的主要因素,设计时要进行仔细的计算,并加以合理地控制和调配。在激振功率放大器中,常使用大功率输出变压器,尤其是输出级由电子管构成时,输出变压器更是不可缺少的关键部件。在晶体管功放中,有时它也是必需的,例如功放在随机信号激励下,为了将更高的蜂值电压供给振动台的驱动线圈,需要外附输出变压器。在设计这种变压器时,要对几种所选择的方案的漏感和分布电容进行反复的计算。在多 In broadband transformers, leakage inductance and distributed capacitance are the main factors affecting high frequency performance. The design should be carefully calculated and properly controlled and deployed. In the exciting power amplifier, often use high-power output transformers, especially when the output stage is composed of a tube, the output transformer is an indispensable key component. In transistor power amplifiers, it is also sometimes necessary. For example, a power amplifier with a random signal excitation needs an external output transformer in order to supply a higher voltage level to the drive coil of the shaker. In the design of this transformer, the leakage inductance and distributed capacitance of several selected solutions should be calculated repeatedly. In more
