In recent years, Piezoelectric Transformers (PTs) have become a great success due to their excellent properties, especially in applications requiring high voltage. The Rosen-type PT is well known for this performance, as its voltage gain at the reson

Introduction. Pulse regulators are widely used to match the output resistance of the source with the load resistance in order to ensure the possibility of taking maximum power when the value of the load resistance changes. Problem. In the case of usi

The problem of non-ideal inertia of the photovoltaic energy storage system (PVESS) may occur due to unreasonable voltage control parameters. In response to this issue, this paper establishes an equivalent reduced-order model (EROM) for PVESS. This ER

Considering the secondary power fluctuation, usually, it is necessary to cascade the second harmonic current suppression circuit (SHCSC) in the front of the single-phase inverter. However, it may result in the cascaded system being unstable, so far,

Doubly-fed induction generator (DFIG) of wind generation system is generally located at the end of the distribution power-grid. Under the weak power grid, the grid connection of wind turbines is unstable, and the current quality is poor. Based on DFI

Compared with a single energy harvester, this tuning fork double-armed cone-shaped flexure transducer can fundamentally solve the problems of high resonance frequency, low output efficiency, and narrow bandwidth of the flexure transducer. Since the t
