Hand tool accumulator device i.e. lithium ion accumulator, for workpiece-adjusting machine, has secondary induction charging device with load electronic unit with rectifier circuit for generating direct current from alternative current

摘要

The device has a secondary induction charging device (12) including a cell unit and a load electronic unit (16), where the load electronic unit includes a rectifier circuit for generating direct current from alternative current. The rectifier circuit is formed by a voltage multiplier chain. The rectifier circuit is formed by a voltage doubler circuit. A load solenoid coil (20) forms a part of the rectifier circuit. The rectifier circuit includes two capacitors that are electrically connected with an electrode by using a purely Ohm's component. An independent claim is also included for a system to transfer.
