Current Feedback-Based High Load Current Low Drop-Out Voltage Regulator In 65-Nm Cmos Technology, Melody Teoh
Current Feedback-Based High Load Current Low Drop-Out Voltage Regulator In 65-Nm Cmos Technology, Melody Teoh
Master's Theses
The motivation for this paper was to design a current feedback-based high load current, low drop-out (LDO) voltage regulator. A bandgap voltage reference (BGR) was also designed in conjunction with the LDO to simulate realistic environments. The schematic was designed with Cadence Virtuoso Schematic XL, using the Taiwan Semiconductor Manufacturing Company (TSMC) 65-nm CMOS library, used for Internet of Things (IoT) System on Chip (SoC) applications. The proposed capacitor-less LDO with BGR provided an average temperature coefficient (TC) of 13.34 ppm/℃ within the range of -40 to 125 ℃. This was in accordance with military standards to gain a higher …

Application Of Model Predictive Control In Modular Multilevel Converter For Mtpa Operation And Soc Balancing, Mohit Sharma
Master's Theses
In this thesis, a one-step horizon model predictive control strategy (MPC) is implemented in a multilevel modular converter (MMC) to control the speed of an electric vehicle (EV) motor. Maximum torque per ampere (MTPA) and field weakening (FW) control strategies are used to generate reference signals for maximum torque output. The proposed control scheme aims to track the reference signal by independently regulating voltages from the MMC modules. To achieve this, the switches of the MMCs are directly controlled, eliminating the need for a pulse width modulator. A one-step horizon implementation of MPC ensures the robustness of the control system …
