Abstract
Step-down DC-DC converters are widely used in modern electronic devices. This article describes a developed diagnostic system and proposes a method for predicting the pre-failure state of DC-DC converters based on measuring and analyzing output voltage transients under step-by-step stress and various temperature conditions (from -40 to +60 °C). It is shown that the degradation of key components (MOSFET transistors and capacitors) leads to characteristic changes in the transient parameters: damping coeffi-cient, natural frequency, and rise time. The effectiveness of this approach is experimentally confirmed using electronic cells in locomotive safety systems as an example.
This paper presents the concept of a dc–dc step-down converter for low-voltage applications that features low switching and conduction losses. The topology of the converter contains an input voltage divider composed of three capacitors so that the voltage stress across the transistors is reduced in relation to the inpu...

Electrolytic capacitors are widely used as DC-link components in power electronic converters such as switched-mode power supplies (SMPSs) and inverters; however, they are also among the most vulnerable components, and their capacitance degradation critically affects overall system lifetime. Condition monitoring is chal...
Renewable energy has been rapidly increased in terms of installed capacity. However, the electronic components inside such a system can cause a serious threat such as Electromagnetic Interference (EMI) to nearby sensitive devices/equipment. This paper aims to study on performance of DC-DC boost converter connected to p...

The Cuk converter is widely used in power electronics due to its ability to provide both step-up and step-down voltage conversion with low ripple characteristics. However, conventional designs suffer from increased component count, higher losses, and significant voltage stress on switching devices. In this paper, an im...

Reliable DC power is essential for the continuous operation of battery energy storage systems (BESS) in EV systems. Since these systems require a specific voltage level that many sources cannot directly provide, an efficient voltage-boosting stage is necessary. This paper presents a higher-voltage-gain structure for a...
