Voltage source based voltage-to-time converter

2015 IEEE 58th International Midwest Symposium on Circuits and Systems (MWSCAS), 2015
Voltage-to-time converter (VTC) circuits are used as the core component of single-slope analog to digital converters (ADCs). These VTC circuits have traditionally depended on the use of a constant current source as part of their implementation in order to have good linearity.

Adaptive Grid-Synchronization Based Grid-Forming Control for Voltage Source Converters

IEEE Transactions on Power Systems
This letter presents a grid-forming control with adaptive grid-synchronization capability for voltage source converters (VSCs). The proposed control has both phase-locked loop (PLL) and power synchronization loop (PSL), which makes it exhibit hybrid ...

Nonlinear Modeling and Analysis of Grid-Connected Voltage-Source Converters Under Voltage Dips

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2020
In power systems, voltage-source converters (VSCs) are gradually replacing traditional devices and dramatically changing power system dynamic behavior, as the VSC’s intrinsic high-order nonlinearity and multiple time-scale characteristics.

Adaptive control of a Voltage Source Converter

CCECE 2010, 2010
This work presents a new trajectory tracking control strategy for a three phase Voltage Source Converter (VSC). The design is based on a third order nonlinear model of the VSC expressed in the dq frame. By suitable approximation of the dc voltage dynamics, the system is transformable to a LTI form by a nonlinear change of state coordinates.
