Development of a Single-Phase PWM-Based Dc-To-Dc Converter for Electric Bicycle [PDF]
, 2000 An electric bicycle is a bicycle that can be operated automatically or manually. The main difference between an electric bicycle and a normal bicycle is that the speed controller of the DC motor attached to the electric bicycle can control the speed of ...

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.Effective performance evaluation and fault detection in PV strings rely heavily on current–voltage (I–V) curve analysis. Yet, most commercial tracers are prohibitively expensive, interrupt system operation during testing and lack the capability for real‐time monitoring in high‐voltage, high‐power environments.

The Application of Approximate Entropy Theory in Defects Detecting of IGBT Module
Active and Passive Electronic Components, 2012 Defect is one of the key factors in reducing the reliability of the insulated gate bipolar transistor (IGBT) module, so developing the diagnostic method for defects inside the IGBT module is an important measure to avoid catastrophic failure and improves

Engineering Reports, Volume 7, Issue 12, December 2025.A rolling prediction framework based on an adaptive weighted Health Index (HI) is proposed, constructing an interpretable HI by fusing multi‐degradation features with inverse standard deviation weighting. By integrating a Support Vector Regression (SVR) model with a rolling update mechanism of a sliding time window and exponentially decaying weights ...

AC to DC Converter Using Microcontroller [PDF]
, 2009 The aim of the project is to obtain a controlled DC output from a standard single phase 230V, 50Hz power supply. For this we first rectified the ac voltage using four diodes. Then the rectified DC voltage is used to get controlled DC voltage output using

Analytical modeling of device-circuit interactions for the power insulated gate bipolar transistor (IGBT) [PDF]
IEEE Transactions on Industry Applications, 1990 The device-circuit interactions of the power insulated gate bipolar transistor (IGBT) for a series resistor-inductor load, both with and without a snubber, are simulated. An analytical model for the transient operation of the IGBT, previously developed, is used in conjunction with the load circuit state equations for the simulations.

Thermal Design of Power Electronic Circuits [PDF]
, 2016 The heart of every switched mode converter consists of several switching semiconductor elements. Due to their non-ideal behaviour there are ON state and switching losses heating up the silicon chip.
