Research on Unified Method of SVPWM and SPWM for ANPC-5L Inverters

2023 3rd International Conference on Electrical Engineering and Control Science (IC2ECS), 2023
The unified theory between sinusoidal carrier based modulation (SPWM) and space vector pulse width modulation (SVPWM) in Active Neutral-Point-Clamped 5-level inverters (ANPC-5L) still lacks systematic analysis and research.

A Double-Modulation-Wave PWM With Reduced Dependency on Current Polarities for Dead-Time-Effect Elimination in Three-Level T-Type Converters

IEEE transactions on power electronics, 2021
No dead-time is contained in the existing dead-time elimination pulsewidth modulation (PWM) for three-phase three-level T-type converters, where complementary drive pulses are allocated alternatively according to polarities of output currents ...

Solution of the Convex Optimization Problem for Subcarrier Wave Continuous-Variable Quantum Key Distribution Protocol with Discrete Modulation

2023 Wave Electronics and its Application in Information and Telecommunication Systems (WECONF), 2023
This paper introduces an approach to solving the convex optimization problem for subcarrier wave continuous-variable quantum key distribution (QKD) protocol using discrete modulation. For the first time, we provide a solution to this problem.

Exotic wave patterns in Riemann problem of the high‐order Jaulent–Miodek equation: Whitham modulation theory

Studies in applied mathematics (Cambridge), 2022
The Riemann problem of the high‐order Jaulent–Miodek (JM) equation with initial data of step discontinuity is explored by Whitham modulation theory, which is a modified version of the well‐known finite‐gap integration method.
