| Abstract |
The simple a 3 transistors (3 T) and 18 diode (18D) system supply dc voltage operates as a three phase controlled rectifier (TPCR). The rectifier ac input current is nearly sinusoidal and its displacement angle is equal to 0. As the system is symmetrical the analysis of current control is described only for an angle pi/3 i.e. 0< wt< pi/3. The method of comparison per unit reference and available space vector current derivatives gives information about ability to control: sinusoidal amplitude of supply ac current, displacement angle and output dc voltage as a function of ac side inductance and per unit load current. The unity power factor is a main state of rectifier, however the leading and lagging operation is possible too. The analysis results, simulation study and laboratory tests of the TPCR rectifier system are presented. |
