  • Patent number: 9425011
    Abstract: Provided is a system for soft switching of an electromechanical relay in a lighting control system using a sensor to detect a specified non-zero position in the electrical input waveform. Following this non-zero position, an adaptive time delay is applied before activation of the relay coil. An error detection circuit measures a time error between relay operation and the zero electrical input condition. This error signal is used to update the adaptive time delay for future relay operations. Using such a procedure has been shown to limit electrical stress on the relay, and therefore lengthen its life.

A controller may command the inverter feed path and the bypass feed path based at least in part on information relevant to the stability of the power source that supplies the first inverter feed path or the first bypass feed path, or both. This information relevant to the stability of the power source may derive from at least one information provider external to the UPS system.

  • Patent number: 9425158
    Abstract: Rigid-flex-type circuit-board structure and manufacturing method, in which a flexible membrane (20) and a sacrificial-material piece (16) are attached to an insulator membrane (12) in the location of the flexible zone (13). An insulator layer (1), which encloses within itself a sacrificial-material piece (16) is manufactured on the surface of the conductor membrane (12). The flexible zone (13) is formed in such a way that an opening (9) is made in the insulator layer (1), through which the sacrificial-material piece (16) is removed. The flexible zone comprises at least part of the flexible membrane (20) as well as conductors (22), which are manufactured by patterning the insulator membrane (12) at a suitable stage in the method.

  • Patent number: 9425706
    Abstract: A three phase inverter consisting of three single phase legs using either switch mode or linear control is fed by a DC-DC converter to provide input output isolation. This requires that the DC-DC converter delivers equal positive and negative voltages to the single phase legs to allow each output to generate a high fidelity sine wave outputs to the load. By measuring the error voltages on the positive output, the negative output and the total output of the DC-DC converter it is possible to control a single duty cycle while maintaining all three output voltages within the limits required by the DC-AC phase legs. This significantly reduces the cost and complexity of the DC-DC converter and eliminates the need to use a fourth phase leg to generate the neutral connection for a three phase output.

  • Patent number: 9425786
    Abstract: A gate driver circuit for the power switch is disclosed. The gate driver circuit includes a resistor network coupled to the power switch. The resistor network includes a plurality of resistors and a control unit operatively coupled to the resistor network. The control unit detects an occurrence of a commutation phase and a saturation phase based on an identity of the power switch and corresponding time stamps associated with a start of a delay phase, the commutation phase, and the saturation phase. The control unit further controls the resistor network to provide different resistance values in at least two of a delay phase, a commutation phase, and a saturation phase when the power switch is transitioned to a first state. A method for driving the power switch is also disclosed.
