AC motor speed performance improvement using fuzzy logic control
… by controlling the firing angle delay of the triac. This controller system is implemented and simulated using MATLAB Simulink software. The performance of the single phase induction motor are investigated and compared with the PID controller. Based on the simulation, fuzzy logic controller is …

Computer aided design and construction of a multi-point positioning actuator system
… supply units (PSU) have been studied. One is a triac controlled a.c. line phase controller. The other is a single-phase variable-frequency-variable-voltage a.c. converter using PWM technology. Both PSUs’ output voltage can be controlled by a DSP board configured as a closed loop control system. …

Design and Testing of a SiC-based Solid-State Bypass Switch for 1 kV Power Electronics Building Blocks
… using additional bypass switches. Conventionally TRIACs and vacuum switches are employed as bypass switches that operate in the range of 2-10 microseconds. Despite having performance advantages, MMCs are still not fully employed in aerospace and naval industries due to their enormous size. Many …
