Abstract: A multi-phase resonant power converter includes: a power stage on a primary side of the multi-phase resonant power converter, the power stage including bridge converter legs each configured to receive an AC input voltage and implement a separate phase of the power converter; a transformer device having a primary side winding for each bridge converter leg and a secondary side winding for each primary side winding; a power circuit electrically connected to the secondary side windings on a secondary side of the multi-phase resonant power converter; a primary-side controller configured to operate the bridge converter legs at a switching frequency; and a separate resonant tank electrically connected to a midpoint of each bridge converter leg. Each resonant tank includes a resonant capacitor in series with the primary side winding for that bridge converter leg. A resonant frequency of each resonant tank is tuned to within +/?50% of the switching frequency.

Abstract: To reduce switching losses, an inverter circuitry of this disclosure may operate using triangular current mode (TCM) control for the semiconductor devices to achieve zero voltage switching (ZVS) at the turn-on of the semiconductor switches. In contrast to other techniques, such as operating the inverter circuitry in continuous conduction mode (CCM), switching devices experience hard switching (usually associated to body-diode hard commutation) at turn-on, and therefore experience the associated switching losses. The inverter circuitry of this disclosure is controlled by processing circuitry, which is configured to apply a smart frequency modulation scheme that enables TCM operation.

Abstract: A modular deflection device comprises a housing and at least two steering elements for applying a steering action on discrete products moving along a conveyor plane. Each steering element has a swivel section formed about a swivel axis with an associated steering section. A drive with a drive element is provided in the housing for each steering element, each drive element being coupled or capable of being coupled to the swivel section of the associated steering element in such a way that the steering element is set into a swivelling movement about the swivel axis by an advancing movement of the drive element. The steering elements are arranged with their swivel sections outside the housing and a section of each drive element can be pushed in an advancing movement along a straight advancing direction with respect to the housing through its own passage opening leading out of the housing.

Abstract: Disclosed is a current source inverter that includes a combination of normally-on and normally-off switches configured to provide free-wheeling paths for current in case of loss of control signals or gate drive power.

Abstract: A sorter for sorting out discrete products includes an arrangement of adjacent sorting fingers. The sorting fingers, depending on pivoted positions, open a sorting gap in a conveying path for bad products to be sorted out or else close the sorting gap in order to support the further conveying of good products.

Abstract: The invention concerns a sorter having a base element that can be swiveled around a horizontal swivel axis with a number of support surfaces uniformly arranged about the swivel axis. Each of the support surfaces can be swiveled into a conveyor for conveying a product along a product stream and swiveled out of the conveyor for ejection of a product from the product stream.

Abstract: A conveyor and process for transporting products, wherein a carrier with an associated product holder can be moved along a conveying path by means of a conveyor element. In a processing position, the carrier can be aligned by means of first alignment elements, and second alignment elements are provided for aligning the product holder for disengagement from the carrier.
