Use PWM for pressure compensation from a fixed-displacement pump
Aug. 2, 2012
Design and build your own low cost, but efficient constant-pressure power units for both servo and conventional applications. Say goodbye variable-displacement pumps.
This is a detailed engineering study of a pressure compensated system that uses a fixed-displacement pump, but no relief valves. It is as efficient as a conventional pressure-compensated pump. You can read about the very complete test results, but more importantly, you can learn all you need to design and build your own low cost, but efficient constant-pressure power units for both servo and conventional applications. Goodbye, variable-displacement pumps.
