The current transformation of the domestic energy landscape, including local generation, new consumption and storage, requires rethinking our research approach. This paper reports experiences from two case studies with their implications for future HCI research in the home. Introduction The home energy environment, as part of the smart grid implementation, is starting a deep mutation: (i) house...

Conventional circulating current (CC) control schemes of the modular multilevel converters (MMC) typically suppress CC to zero reduce system loss. However, non-zero can also bring additional benefits. In this paper, a peak arm minimization method MMC using multiple injection (MCCIC) is studied. Specifically, second-order (SOCC) and fourth-order (FOCC) are used achieve purpose. Firstly, amplitud...

The control of bull spermatozoon flagellar activity has been investigated using direct current injection into the cells through an impaling glass microelectrode. Negative current injection results in a decrease in the flagellar frequency. Flagellar frequencies can be decreased to zero with high negative currents. This current injection response is dependent on the magnesium concentration availa...

A novel current injection network for low-harmonic rectifiers that apply the third harmonic current injection is proposed in this letter. The current injection network requires one inductor, two capacitors, and one 1 : 1 transformer with voltampere rating of only 0.16% of the input power. The transformer is introduced to provide complete rejection of harmonic components of the injected currents...
