  • Patent number: 9473044
    Abstract: A power inverter includes a DC/AC inverter having first, second and third phase circuitry coupled to receive power from a power source. A controller is coupled to a driver for each of the first, second and third phase circuitry (control input drivers). The controller includes an associated memory storing a phase skipping control algorithm, wherein the controller is coupled to receive updating information including a power level generated by the power source. The drivers are coupled to control inputs of the first, second and third phase circuitry, where the drivers are configured for receiving phase skipping control signals from the controller and outputting mode selection signals configured to dynamically select an operating mode for the DC/AC inverter from a Normal Control operation and a Phase Skipping Control operation which have different power injection patterns through the first, second and third phase circuitry depending upon the power level.

  • Patent number: 4628689
    Abstract: An exhaust system for the internal combustion engine of an automotive vehicle comprises a diecast housing of an aluminum-magnesium-silicon alloy in the form of a boxlike housing part provided with a removable cover affording access to a replaceable rectangular parallelepipedal filter cartridge which separates the housing into an intake chamber and a discharge chamber respectively connected to an expansion chamber and the tail pipe.
