| Number | Title | Issue Date |
| 7282887 | Laser diode triggered soft start controller for a polyphase electric motor A solid state soft start controller system has a power supply, an electric motor, a thyristor electrically interconnected between the power supply and the electric motor so as to selectively allow current to pass from the power supply to the phases of the electric m... | 10/16/2007 |
| 7259544 | Load symmetrization with controllable inductor A method for compensation and symmetrization of a three-phase system with a single-phase load is provided. At least one variable inductor for connection to the three-phase system is employed in the method. The inductor's inductance is adjusted to obtain a resistive ... | 08/21/2007 |
| 7260452 | Apparatus, method and computer program product for monitoring AC line current through the step start resistors of a high voltage power supply A circuit to monitor ac line current through resistors employed to provide a ‘step start’ in a power supply, including means to monitor the current flowing through the step start resistors, comprising a peak detector, a sample and hold circuit, an analog to digi... | 08/21/2007 |
| 7050278 | Motor controller incorporating an electronic circuit for protection against inrush currents Inrush currents in the dc intermediate circuit of a motor controller necessitate the incorporation of protection circuits. These circuits usually take the form of a resistor inserted in series with the intermediate circuit, and the resistor is short-circuited after ... | 05/23/2006 |
| 6788023 | Motor starter circuit, particularly for refrigerator compressors A starter circuit for motors, particularly for refrigerator compressors, comprising a starter device which is adapted to be connected to a starter winding and to a steady-state winding of an asynchronous motor, the windings being in turn connected to a power supply ... | 09/07/2004 |
| 6781342 | System and method for soft starting a three phase motor A three phase motor starting system is provided to reduce the in-rush current to the motor in order to obtain a soft start of the motor. The soft start of the motor equates to reduced impact forces on motor parts and device components connected to the motor during s... | 08/24/2004 |
| 5428493 | Motor starting relay device having PTC thermistors In a relay device, a first PTC thermistor has one end connected to a first external connecting terminal, and the other end connected to one end of a second PTC thermistor, the other end of which is connected to a second external connecting terminal, and t... | 06/27/1995 |
