The equipment connected to an electricity distribution network usually needs rectification. The conventional single phase diode rectifier uses a large electrolytic capacitor to reduce DC voltage ripple, which produces a non-sinusoidal line current. So power factor correction (PFC) techniques are gaining attention now a day. The boost topology is most popular than others in PFC applications. Thi...

A remaining useful life prediction methodology for electrolytic capacitors is presented. This methodology is based on the Kalman filter framework and an empirical degradation model. Electrolytic capacitors are used in several applications ranging from power supplies on critical avionics equipment to power drivers for electro-mechanical actuators. These devices are known for their comparatively ...

This study compares ripple port, stacked switched capacitor, and capacitive energy storage architectures for active power decoupling, comparing the number of components, performance, density, DC-link capacitor reduction, efficiency, frequency operation to highlight their main benefits drawbacks single-phase grid-connected applications. The overview reveals equivalent effective density without e...

Efficiency and recuperation capabilities of modern electrical drives have become very important features within variable speed drive applications. Regenerative electrical drives are therefore usually equipped with cost extensive pulsed active front end topologies for the recuperation mode. Contrarily, the much cheaper fundamental frequency switched front end is used. It has no electrolytic capa...

This paper proposes a method to obtain a protected voltage gain by employing a protection circuit for the voltage doubler or multiplier circuit in an isolated tyde DC-DC Converter. The entire set up consists of a phase shift converter with a protected bridge/voltage doubler rectifier on the output side. The operating frequency of the phase shift converter is 20-25kHz (depending on the requireme...

This paper proposes a single-phase, single-stage common-ground inverter with non-electrolytic capacitor and buck-boost ability. The proposed is employed by boost stage DC-DC converter bimodal circuit, which makes it satisfactory for PV systems wide input voltage range lower switch stress. leakage current of the can effectively suppress because parasitic between panel ground shortened. In additi...

Electrolytic capacitor-less drive systems have a higher lifespan and reliability. However, the DC-link voltage of ECL has sudden change under dynamic conditions, which results in serious degradation system performance. To solve problem, this paper proposes model predictive current control (MPCC) based on motor power change. A grid is established. Motor introduced into cost function, so that can...
