Abstract

Circuits and methods that solve the light-load problem of a multi-level converter by generating a ripple signal in the control loop of the multi-level converter that causes a large output current ripple during light load conditions. This added current ripple does not change the average output current but does create a temporary positive and negative current that can be used to balance and charge/discharge the fly capacitors of the multi-level converter. An alternative approach is to add extra switching cycles for the fly capacitors when the output ripple current crosses zero.

Abstract

A rotating electrical machine (10) is mounted on an electric cutting tool with a cutter. The rotating electrical machine (10) is provided with a motor body (20) that transmits rotational force to the cutter, and a control unit (30) that controls an input current to the motor body (20). The control unit (30) controls the input current so that the motor body (20) operates at a maximum rotation speed during no-load operation in a startup state. When the cutter starts cutting a cutting object so that a load is applied to the motor body (20) and the rotational speed reaches an initial stable state, the control unit (30) controls the input current to the motor body (20) so as to maintain the rotational speed. The control unit (30) increases the input current when the rotational speed decreases after the initial stable state in a region where the input current does not reach an upper limit value, and decreases the input current when the rotational speed continues for a switching threshold time or longer.

Abstract

A switching power converter architecture that is efficient across its entire power range, regardless of load level, by partitioning the power devices into segments for optimal gate drive and providing a local variable-voltage driver for each power device segment. Power device segments may be selectively enabled or disabled based on the level of power to be delivered to a load. In addition, an adaptive gate drive scheme enables dynamic control of the RON and QG values for each power converter device so that the power devices may operate at the lowest RON value at or near maximum power levels for reduced conduction losses, at the lowest RON×QG product value at mid-level loads for peak efficiency, and at the lowest QG value at light loads for reduced switching losses.

This method for separating and recovering comprises: (A) a step for preparing an unfired waste before production degreasing, which contains a magnetic metal powder, a ceramic powder, a rare earth powder, and a resin component, and in which the metal powder and the ceramic powder are at least partially adhered to each other; (B) a step for refining the unfired waste before production degreasing by pulverization; (C) a step for separating and recovering a metal powder-containing material and a rare earth powder-containing material by means of a magnet after the step (B); (D) a step for producing a rare earth component-containing solution, in which the rare earth powder is dissolved by dissolving the rare earth powder-containing material into a mineral acid; (H) a step for producing a metal component-containing solution, in which the metal powder is dissolved, by dissolving the metal powder-containing material into a mineral acid; and (E) a step for recycle degreasing the resin component from the unfired waste before production degreasing between the step (A) and the step (D) and between the step (A) and the step (H).

Abstract

The present invention provides a method for separating and recovering a rare earth component and a metal component from a post-calcination waste. This separation and recovery method includes: (A) a step for preparing a post-calcination waste of a multilayer ceramic capacitor in which a ceramic layer, an internal electrode layer containing a first metal component that has magnetic properties, and a baked electrode layer containing a second metal component that does not have magnetic properties are sintered; (B) a step for refining the post-calcination waste; (C) a step for separating and recovering, with use of a magnet, a first separated material that contains a refined ceramic and a refined first metal, and a second separated material that contains a refined ceramic, a rare earth-containing material, and a refined second metal; (D) a step for dissolving the second separated material into a mineral acid that has no oxidizing power, and precipitating the refined ceramic and the refined second metal, thereby generating a rare earth component-containing solution in which the rare earth component in the rare earth-containing material is dissolved; and (E) a step for dissolving the precipitate in the second separated material into ammonia water, thereby generating a second metal solution in which the second metal component in the refined second metal is dissolved.

Abstract

This invention provides a multilayer ceramic capacitor with which a sufficient strength can be obtained. A multilayer ceramic capacitor (1) is provided with: a stack (2) including six surfaces from a first surface (11) to a sixth surface (16); a first external electrode (21); and a second external electrode (22). The stack (2) is provided with an inner layer part (53) and two outer layer parts (50) arranged so as to sandwich the inner layer part (53) in the stacking direction (100). The outer layer part (50) is provided with an outer layer dielectric layer (41), and contains fibers (60) in the outer layer dielectric layer (41).
