随着四个现代化建设的需要,许多科研部门和工厂要配置一些大功率的稳定电源。其功率小则数千瓦,大则数十千瓦。过去,这类设备均采用直流发电机,然后以反馈放大器控制其激磁绕组的电流来实现自动调整的。特别是对那些输出电压较高的场合多取此方案。这种成套设备的缺点是占地面积大、马达噪声很响,而电源功辜利用效率却不高,操作和维修也比较复杂。随着新型电子器件的发展,自六十年代初,国外已陆续出现一些全晶体管的大型稳定电源。其设计功率越来越大,最大直流输出功率竞高达数百千瓦。本文所介绍的这台全晶体管大功率稳压和稳流两用电源的电路是比较典型的,其特点是输出功率大(设计功率为9.6千瓦,实际可超过10千瓦)。最大输出
With the needs of the four modernizations, many scientific departments and factories have to deploy some high-power and stable power supplies. Its power is small, several kilowatts, then tens of kilowatts. In the past, these devices are used DC generator, and then feedback amplifier to control the excitation winding current to achieve automatic adjustment. Especially for those high output voltage occasions to take this program more. The disadvantage of this kind of complete set of equipment is that the area is large, the noise of the motor is very loud, but the utilization of the power is not high, and the operation and maintenance are complicated. With the development of new electronic devices, some large stable power transistors of all transistors have appeared one after another in foreign countries since the early 1960s. Its design power is bigger and bigger, the maximum DC output power is up to hundreds of kilowatts. The circuit of this all-transistor high-power regulated and regulated dual-purpose power supply introduced in this paper is typical. It features large output power (designed power of 9.6 kW and actually over 10 kW). Maximum output
