    Abstract: An electronic device includes a base substrate, and a plurality of battery substrates constructed from mica and being attached to the base substrate. An aggregate area of the base substrate is greater than an aggregate area of the plurality of battery substrates. The electronic device also includes a plurality of active battery layers, each active battery layer being attached to a different respective battery substrate, with each active battery layer having a smaller area than its corresponding battery substrate. A film is disposed over the plurality of active battery layers and sized such that the film extends beyond each active battery layer to contact each battery substrate, and such that the film extends beyond each battery substrate to contact the base substrate.

    Abstract: An AC/DC converter includes a first terminal and a second terminal to receive an AC voltage and a third terminal and a fourth terminal to deliver a DC voltage. A rectifying bridge is provided in the converter. A controllable switching or rectifying element has a control terminal configured to receive a control current. A first switch is coupled between a supply voltage and the control terminal to inject the control current. A second switch is coupled between the control terminal and a reference voltage to extract the control current. The first and second switches are selectively actuated by a control circuit.

    Abstract: A battery encapsulation method includes disposing an active battery layer on each of a plurality of battery substrates, with each battery substrate having a greater area than its corresponding active battery layer. The plurality of battery substrates are attached to an interposer having a greater area than an aggregate area of the plurality of battery substrates. The active battery layers are environmentally sealed by disposing a film over the active battery layers sized such that the film extends beyond the active battery layers to contact the battery substrates and the interposer. The interposer is physically along locations where the film contacts the interposer so as to form a plurality of battery units, with each battery unit including one of the battery substrates with the associated active battery layer disposed thereon and being environmentally sealed by the film.

    Abstract: A reversible converter includes a first field effect transistor and a second field effect transistor coupled in series between a first terminal and a second terminal for a DC voltage. A first thyristor and a second thyristor are coupled in series between the first and second terminals for the DC voltage. A third thyristor and a fourth thyristor are also coupled in series between the first and second terminals for the DC voltage terminals, but have an opposite connection polarity with respect to the first and second thyristors. A midpoint of connection between the first and second field effect transistors and a common midpoint of connection between the first and second thyristors and the third and fourth thyristors are coupled to AC voltage terminals. Actuation of the transistors and thyristors is controlled in distinct manners to operate the converter in an AC-DC conversion mode and a DC-AC conversion mode.
