摘要： A low voltage AC power controller uses a line coupled capacitor AC to DC converter circuit to obtain energy from AC line power supplied to an AC load and may be used with an external high voltage AC switching device to control power supplied to the AC load. The line coupled capacitor AC to DC converter circuit provides a low power device that senses characteristics of the power supplied to the load and can communicate sensed information and/or receive control information related to the power supplied to the load.

摘要： Current flowing through an inductor on a primary side of a voltage converter is sensed and compared to a threshold peak current value to determine when to end an ON portion of the voltage converter. The secondary side of the voltage converter supplies an indication of output voltage for use in determining the threshold peak current value. On start-up the primary side detects when the indication of output voltage is supplied by the secondary side across on isolation channel. Prior to detecting the indicating is being supplied, the primary side uses an increasing threshold peak current as the threshold peak current value. After detection that the indication of output voltage is being provided by the secondary side, the threshold peak current value is based on the indication of the output voltage.

摘要： A method includes supplying a current to at least one conductive path integral with a MEMS device to thereby exert a Lorentz force on the MEMS device in the presence of a magnetic field. The method includes determining the magnetic field based on a control value in a control loop configured to maintain a constrained range of motion of the MEMS device. The control loop may be configured to maintain the MEMS device in a stationary position. The current may have a frequency equal to a resonant frequency of the MEMS device.
