Abstract: An anti-gravity liquid evaporator comprises a tank body (1). The top surface of the tank body (1) is provided with an upper opening (2), the bottom surface of the tank body is provided with a lower opening (7), the inside of the tank is provided with a liquid spray nozzle (3), and plate-shaped dispersion flaps (8) are mounted in the tank body (1), wherein the dispersion flaps (8) are a plurality of horizontal flow boards (9) extending in a horizontal or inclined direction, and the horizontal flow boards (9) are connected by a vertical flow board (10) or an inclined flow board (16) that is inclined.

Abstract: Systems and techniques for efficient power regulators with improved reliability. A power regulator may include a first driver including a first switch and a second switch, where a power dissipation of the first switch is less than a power dissipation of the second switch. The power regulator may include a second driver. The first and second switches may be implemented as transistors, which may have different on-state breakdown voltages and/or on-state drain source resistances.
