  • PV module cell matrix placement station and methods for removing air or bubbles during the manufacturing process
    Patent number: 9184313
    Abstract: Methods and devices for removing entrapped bubbles or air in photovoltaic solar cells during a manufacturing process including an encapsulation process include, for example, wiggling the photovoltaic solar cells or pushing out air bubbles by applying vibrations and/or light pressures. Optional additional steps include liquid wetting or dispensing to or around the photovoltaic solar cell matrix for air releasing before the placement of the matrix into a liquid for encapsulation.

  • Unipolar drive topology for permanent magnet brushless DC motors and switched reluctance motors
    Patent number: 7049786
    Abstract: A unipolar drive includes a booster, an energy storage module, and a unipolar inverter. The booster increase a voltage received from a power supply to produce an energy output. The energy storage module store at least some of the energy output by the booster. The unipolar inverter energizes windings of a motor using energy from the booster and returns energy from the windings to the booster when the windings are not being energized.
