FAST RESPONSE REGENERATIVE DYNAMOMETERS

This paper describes the regenerative electrical dynamometer. Its main features are: (1) The maximum possible proportion of the engine shaft output energy is recovered and returned as electrical energy to the A.C. mains supply, the converter being always automatically synchronized in voltage, phase and frequency at any engine speed; (2) The double bridge configuration allows the design of a very responsive dynamometer system, which will switch from loading to motoring rapidly; (3) As the dynamometer can also be used to provide motoring torque, it may be used to start the engine or turn the engine at high speed (with no fuel supplied to it) so as to measure friction losses, check valvegear, lubrication, etc.; (4) The torque readout system utilizes the well understood and accepted swinging frame machine which is easy to calibrate; (5) There are other advantages in that the test rig is extremely easy to use and easily interfaced to a computer or microprocessor system.
