Battery charger ICs are integrated circuits (IC) that are used to charge batteries

Electrical contacts and contact materials are soft, high-conductivity, oxidation- resistant materials that are used in circuit breakers, relays, switches, and electrical discharge machining (EDM) applications.

Battery and fuel cell test equipment consists of specialized test stations, stands or systems, monitors and component modules for performance or endurance testing.

AC to DC converter chips transfer an AC input into DC power using switching (MOSFET, IGBT) or rectification (diodes, Schottky diodes).

Power supplies are devices that produce AC or DC power.

DC to AC converter chips transfer a DC input into AC power by using switching, inversion, or other technology.

Current limiting diodes (CLD) regulate current over a wide voltage range.
