This work demonstrates the feasibility of integrating a MESFET with CMOS PWM circuitry for a completely integrated SiC driver thus eliminating the need for the intermediate buffer stage. Due to the easy integration of MESFET s into SOI CMOS processes, MESFETs can be fabricated alongside MOSFETs without any changes in the process flow. To drive the JFET, the MESFET was DC biased and then driven by a 1.2V square wave PWM signal to switch the JFET gate from 0 to 10V at frequencies up to 20 kHz. Characteristic curves for the MESFET were measured up to 250☌. The wide operating temperature range and high breakdown voltage of up to 50V make the SOI MESFET ideal for power electronics in extreme environments. In this work a discrete silicon-on-insulator (SOI) metal semiconductor field effect transistor (MESFET) was used to drive the gate of a SiC power JFET switching a 120V RMS AC supply into a 30Ω load. As a result an intermediate buffer stage is required between the CMOS circuitry and the JFET.
Advanced CMOS microcontrollers are ideal for PWM signals but are limited in output voltage due to their low. These devices require external drive circuits to generate pulse width modulated (PWM) signals switching from 0V to approximately 10V. Silicon Carbide (SiC) junction field effect transistors (JFETs) are ideal for switching high current, high voltage loads in high temperature environments. Simulation and experiment results show that the DTC method can minimize the torque ripple of BLDCM effectively and gain rapid dynamic response. In this paper, DTC is used to control the BLDCM, in the purpose of reducing the torque ripple. Finally, with tins control signal and the state of fluxlink, the corresponding voltage space vector is selected, so that the torque can be controlled directly. And then the control signal is obtained by inputting the error to the controller. This method observes the fluxlink and torque of the motor in the stator coordinate, and compares the observed values with the set values to obtain the error. The direct torque control (DTC) can control the torque instantly. However, torque ripple generated in commutation period is the main drawback of BLDCM, which make the application of BLDCM in the high accuracy system impossible. Permanent magnet brushless DC motors (BLDCM) have been more and more widely used in industry applications because of their advantages such as higher ratio of power to volume, lower noise and easier maintenance compared to permanent magnet DC servo motors. Also, the effectiveness of the proposed PC-SDC system is investigated by a comparison between pulses count that is measured practically by FSMM system and real pulses count that is gathered from an oscilloscope. Real-time feature is investigated via two performance metrics ART and SMT. These rules control DC motors according to previous moving state and next required moving state. The second system is μC-based motor control module (MCM) to control this DC motor via different intelligent rules. The first system is μC-based feedback speed monitoring module (FSMM) system which collects speed data (i.e., pulses count) for this DC motor by using a PIC μC-based encoder sensory system. CPDDI can control DC motor via bi-directional communication channels with two practical in-house designed firmware systems.

The suggested CPDDI model is the real software implementation of moment perspective of a new intelligence model called “Accumulative Intelligence”. Intelligence feature is achieved by applying the collect-process-decide-deliver-instructions (CPDDI) model. Open architecture feature refers to apply the same firmware components of this PC-SDC with different types of DC motors and sensory systems. Developing PC-SDC is dependent on open architecture and intelligence features. This paper presents a practical PC-based speed and direction controller (PC-SDC) for controlling DC motors.
