  • Patent number: 10411474
    Abstract: An electric power system includes a variable-frequency drive and a control module. The variable-frequency drive includes a first power converter, a second power converter and at least one energy storage module. The first power converter is connected between a DC bus and a power terminal. Moreover, electric energy is transferred between the first power converter and the power terminal at a first power. The second power converter is connected between the DC bus and an electric/kinetic energy conversion device. Moreover, electric energy is transferred between the second power converter and the electric/kinetic energy conversion device at a second power. As the second power is dynamically changed, the control module controls a charge/discharge operation of the at least one energy storage module. As a consequence, the operational change of the electric/kinetic energy conversion device is reversely compensated.

  • Patent number: 10263794
    Abstract: The invention pertains to systems where DC power is supplied by a PSE to a PD, such as over differential data wire pairs. IEEE standards require a minimum current to be drawn from the PD in order for the PSE to continue supplying the DC voltage. If the PD is in a low power mode, the PSE will normally discontinue supplying the DC voltage, which then requires a new detection and classification routine for powering up again. To avoid this, a “maintain power signature” controller provides a periodic current pulse by a current source connected between the PD input and the PD's full bridge rectifier. Any droop in the DC voltage that reverse biases the full bridge rectifier while the PD is in its low power mode will not affect the current pulse, so the PSE continues to supply the DC voltage.
