At present, the widespread use of small induction motors for home appliances and other applications justify the development of new drives and motor designs. The aim shall be to save energy and to consume it with a clean absorption of current from the mains. This paper presents an application for the speed control of a small single/two phase induction motor. This application has a cascaded H-bridge...
The widespread use of small induction motors for home appliances and other applications justify the development of new drives and motor designs. The aim shall be to save energy and to consume it with a clean absorption of current from the mains. The basis of the system proposed in this paper is to generate sinusoidal waveforms using digital techniques (they are stored in an EEPROM as reference vectors)...
Accurate high current measurements require the use of devices which are difficult to calibrate since neither it is easy to obtain the current needed nor to set up a proper testing rig in the laboratory. Nevertheless, a straight wire carrying a high current can be replaced by an N-turn coil fed with an N-times lower current. In this paper, the uncertainty associated with the use of N-turn coils in...
