适合学校实验室使用的节能型稳压器设计

摘要

学校实验室精密仪器设备一般都配备稳压器，以保证仪器的正常使用，然而稳压器的能源损耗是一大浪费。如何降低稳压器的能源损耗，让市电在安全电压范围内时，使稳压器自动脱离电源，将市电直接供给负载，消除稳压器自身损耗；负载为零时，也使稳压器自动脱离电源，消除其空载损耗，让稳压器的能源损耗降至最低，又能发挥稳压器应有的作用，经试制，达到了设计功能。%In order to ensure the normal use, school laboratory precision instruments are generally equipped with voltage regulators. However, the use of regulators is a big waste of energy loss. How to reduce the energy loss of voltage regulators by keeping AC in safe voltage range and voltage regulators off the power supply automatically so as to enable AC to supply load directly? When the load is zero, regulators can also automatically cut from the power supply and eliminate the no-load loss. The energy loss of voltage regulators has been reduced to the lowest point and the due functions of regulators have been ensured. The trials prove that the design has achieved desired purposes.
