Analysis of Power Flow in a Power Converter.
IEEJ Transactions on Industry Applications, 1996 Power converters have been widely used in many industrial applications. On the ac-side of such converters, the current is distorted because of the nonlinearity of the power devices even when the source voltage is sinusoidal. This leads that the power converter is regarded as a harmonic-current source.

Beaming power: Photovoltaic laser power converters for power-by-light
Joule, 2022 Photovoltaic laser power converters (PVLPCs) are the core element of power-by-light (PBL) systems, which are basically made up of a power laser, an optical fiber, and a PVLPC. PBL allows the safe transfer of power in situations where the direct use of electrical energy to power electronic equipment is either not possible or not recommendable. The first

Energies, 2022 Universal power converters (UPCs) have aroused significant attention in performing multiple operations in a single power converter. Furthermore, they contribute to economic operation and improved system performance. In this work, a new configuration of the universal power converter (UPC) was proposed by using a simple switching arrangement.
