Patent CA-2649605-A1 (CA)
Title: A processing method and apparatus for energy saving of an active infrared induction instrument powered by dry battery
Inventor: WEIGEN CHEN
IPC: H03K17/945
Filed: 2007-04-19
Abstract: An active infrared induction instrument powered by a dry battery capable of reducing power consumption through the adjustment of the emitter pulse width. The infrared emitting LED emits infrared signals, which, after being reflected by an object, are received by the infrared photodiode. The infrared signals received by the infrared photodiode then enter an integrated circuit chip through a comparator. The pulse widths of the infrared emission pulse signals are dynamically adjusted after the width of the pulse series is received by the discrimination chip, thus reducing the emission power consumption to save energy.

Abstract: Provided is a maximum power point (MPP) tracker for a PV cell inverter, and a PV cell inverter. The MPP tracker decouples output power oscillations from the input power generation and extracts maximum available power from the PV cell. The PV cell inverter uses the MPP  tracker and generates a sinusoidal output current from the MPP tracker output.  The sinusoidal output current may be fed to a power distribution grid. The PV cell inverter may use a pulse width modulation technique to cancel harmonics in the sinusoidal output current. The circuits use a minimum number of components and avoid use of large electrolytic capacitors.
