The control circuit is based on a fixed value AC capacitor within a full bidirectional switches bridge PWM\u00a0controlled at much higher than line frequency (in kHz\u00a0range). The power bridge circuit and its embedded pulse\u00a0driver circuit are presented within the theoretical sections of\u00a0the paper. In the experimental section, using a small electric\u00a0motors test bench and a two speed SPIM with auxiliary\u00a0winding, are analyzed the main influences of the pulse drive\u00a0circuit over the ECC. Firstly, being considered that the optimum\u00a0is reached at the maximum motor torque, the optimal\u00a0pulses frequency has been established around 4 kHz.\u00a0Secondly, the switches over-voltages at the ommutations<br \/>\nmoments being a serious drawback of the ECC, are analyzed\u00a0the influence of the fixed capacitor value and the dead\u00a0time of the pulse shape over the MOS-FET power transistors<br \/>\nof the bidirectional switches over-voltages. The overvoltages\u00a0diminish as both the capacitor value and the dead\u00a0time diminish. More than that, in contrast with some authors,\u00a0there are no disadvantages as dead time became zero.\u00a0These issues are the main contributions of this paper.<\/td>\n<td width=\"66\"><a href=\"http:\/\/elth.ucv.ro\/fisiere\/anale\/2015\/2.pdf\" target=\"_blank\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter  wp-image-191\" src=\"http:\/\/elth.ucv.ro\/fisiere\/anale\/wp-content\/uploads\/2015\/03\/images1.jpg\" alt=\"images\" width=\"100\" height=\"104\" \/><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"excerpt":{"rendered":"<p>Abstract The control circuit of an Electronically Controlled\u00a0Capacitor (ECC) for the optimization of the Single\u00a0Phase Induction Motor (SPIM) with auxiliary winding is\u00a0presented.
