开关式液压动力源是作者独创的一种新型节能压力转换系统。主要应用于多执行器液压系统中，安装在液压泵和执行器之间（一个执行器一个开关式液压源）。它可以通过升压或降压来提供与系统中每个执行器的消耗相适应的压力或流量，功率损耗低，方便地通过高速开关阀，就像液压变压器一样。开关式液压源有两种基本类型：增压和降压。介绍了它们的结构和工作原理。通过仿真和实验分析了增压式和降压式两种典型开关式液压源的动态特性。对性能进行了评估，并提出了开关式液压电源效率的改进方案。版权所有 © 2005 by ASME
Switchmode hydraulic power supply is a new kind of energy-saving pressure converting system, which is originally proposed by the authors. It is mainly applied in multiple-actuator hydraulic systems, and installed between hydraulic pump and actuators (one switchmode hydraulic power supply for one actuator). It can provide pressure or flow rate that is adapted to the consumption of each actuator in the system by boosting or bucking the pressure, with low power loss, and conveniently, through high-speed switch valves, just like a hydraulic pressure transformer. There are two basic types of switchmode hydraulic power supply: pressure boost and pressure buck. Their structures and working principles are introduced. The dynamic characteristics of two typical types of switchmode hydraulic power supply, the pressure boost type and the pressure buck type, were analyzed through simulations and experiments. The performances were evaluated, and improvements on the efficiency of switchmode hydraulic power supply were proposed.Copyright © 2005 by ASME
