摘要： A power converter is provided. The power converter includes first to fourth switches electrically connected in series, a flying capacitor and a controller. Positive and negative terminals of the flying capacitor are electrically connected to the second and third switches respectively. The controller operates the first and fourth switches to perform a first complementary switching with a first dead time, and operates the second and third switches to perform a second complementary switching with a second dead time. The controller determines to regulate the first or second dead time by detecting a capacitor voltage of the flying capacitor, such that the capacitor voltage of the flying capacitor is maintained within a balance voltage range.

摘要： An induction cooker includes a rectifying device, a first energy-storage device, a switch device, a second energy-storage device, a heating device and a control device. The capacitance of the second energy-storage device is greater than the capacitance of the first energy-storage device. When the induction cooker is just starting, the control device controls the switch device to be turned off, such that the heating device generates an output current according to an energy of the first energy-storage device. The control device determines whether a pot is on the heating device according to a change state of the output current. When the pot is on the heating device, the control device controls the switch device to be turned on, such that the first and second energy-storage devices are coupled, and the heating device heats the pot according to energies of the first and second energy-storage devices.

摘要： The present disclosure provides a motor drive integrated on-board charger to reduce the quantity of components in an electric system of an electric vehicle. Reduction of components is achieved by utilizing the motor and the motor driving inverter as a part of the on-board charger in the charging mode. By controlling relays, electrical connections of the system may be reconfigured according to its mode of operation. In one aspect, the motor and the motor driving inverter play the roles of a boost PFC, a current regulator, or both.

摘要： A battery module includes battery cells, a housing and a temperature-sensing line. The housing includes a base and a cover. A hollow portion is defined when the base is combined with the cover. The battery cells are fixed by the base and the cover, and a part of the outer periphery of each of the plurality of battery cells is exposed from the hollow portion. The temperature-sensing line includes two conductive wires and an insulating layer disposed between the conductive wires. The temperature-sensing line contacts the outer periphery of each of the battery cells exposed from the hollow portion. When the temperature of any battery cell is increased to a predetermined temperature and heat is transmitted to the temperature-sensing line, the insulating layer is melted at the predetermined temperature to make the conductive wires conduct with each other and generate a warning signal.

摘要： A hybrid power conversion circuit includes a high-side switch, a low-side switch, a transformer, a resonance tank, a first switch, a second switch, a first synchronous rectification switch, a second synchronous rectification switch, and a third switch. The resonance tank has an external inductor, an external capacitance, and an internal inductor. The first switch is connected to the external inductor. The second switch and a first capacitance form a series-connected path, and is connected to the external capacitance. The first and second synchronous rectification switches are respectively coupled to a first winding and a second winding. The third switch is connected to the second synchronous rectification switch. When an output voltage is less than a voltage interval, the hybrid power conversion circuit operates in a hybrid flyback conversion mode, and otherwise the hybrid power conversion circuit operates in a resonance conversion mode.

摘要： A guiding grid is disclosed and includes plural circumferential elements and plural radial elements. The circumferential elements are disposed concentrically relative to a central axis, spaced apart from each other in a radial direction, and form different heights relative to a bottom surface. One of the circumferential elements forms a top height relative to the bottom surface, so that the circumferential elements are divided into an outer-ring region and a central region in the radial direction. The circumferential elements located in the central region are increased in height relative to the bottom surface along the radial direction. The circumferential element located in the outer ring region are reduced in height relative to the bottom surface along the radial direction. The radial elements are connected between each of two adjacent circumferential elements. At least one of the radial elements is misaligned and discontinuous in the radial direction.
