This work provides a detailed discussion about power converter circuits using SiC MOSFET, a classical approach to designing gate drivers for SiC MOSFET, and mitigation of voltage glitch and crosstalk voltage in SiC MOSFET using active as well as passive miller clamp. Different type of gate driver configuration has been discussed in this work. Crosstalk voltage exits on the gate-source terminal of SiC power MOSFET. Active and passive miller clamps are used to eliminate any crosstalk voltage which is available in the switching the MOSFET. As a result of the rapid growth of semiconductor technology, a variety of high-performance semiconductor devices are becoming available for purchase. In recent years, the silicon carbide SiC MOSFET and the junction barrier Schottky diode (JBS) have been created and are now commercially accessible. SiC MOSFETs outperform their silicon counterparts in terms of performance. The voltage and current ratings of the SiC MOSFET have also been shown to be significantly higher than those of the Si MOSFET.

This paper provides different aspects of speed control of DC drive. Different control schemes of DC motor with proper explanation has been provided. Multi-pulse converter and firing angle control scheme has been discussed. Simulation results have been provided for the speed control aspect. It is possible to measure the speed of the motor with a tachometer or incremental encoder. These tachometers and incremental encoders produce erroneous results as a result of a variety of factors. the authors provide a strategy for compensating against imperfections in incremental encoders. In this paper, a study of several speed control systems for direct current motors is discussed in detail. This paper discusses many strategies for controlling the speed of a DC motor, including various speed control schemes. This study discusses and simulates multi-pulse converter-based DC motor speed control. The results of the simulation reveal that the motor can be controlled accurately in terms of speed. The speed of the motor can be measured with a tachometer or incremental encoder.

This paper analyses a multilevel inverter configuration which provides single-phase seven-level output. This topology partially adopts the packed u-cell structure and uses series connected DC sources to generate the required number of output voltage levels. The DC-link capacitors are not required in this topology. The operating modes and modulation scheme of this multilevel inverter are explained in detail. For applications requiring high voltage and high power, multilayer inverters (MLI) are one of the most popular choices. Higher voltage levels can be generated with MLI, despite the fact that lower rating components are used. MLI provides greater voltage level, which minimizes total harmonic distortion (THD), and MLI operates at a lower switching frequency than a standard DC-AC inverter, resulting in lower overall power consumption. There are several alternative modulation approaches for MLI that are dependent on either the fundamental switching frequency or the high switching frequency of the device.

This paper discusses the modelling and control aspects of an enclosed lowest converter-based shunt active power filter. In an AC distribution network, the shunt active power filter reduces harmonic interference. Using an interleaved buck converter architecture prevents the typical inverter’s shoot-through problem. The P-Q control method is utilised to provide compensating current. One loop controls the dc-link voltage while the other regulates the voltage mode. This technique uses a twin-loop architecture. For example, the park transformation and inverse park transformation are used in the current loop to take the load current into account. Current is controlled using hysteresis using a current limiting device. PWM is used to create switching pulses by the gate driver, a digital signal processor. All three parameters of a non-ideal voltage source can be figured out. For an unbalanced nonlinear load, the voltage at the source, the load’s current, and the source’s current have all been provided.
