    摘要： One or more Variable Frequency Drives (VFD) are connected to a packet network and the power transistor drive signals normally generated by the VFD to produce a desired Pulse Width Modulated (PWM) motor drive signal are generated by a software controller located in the packet network and transmitted to the VFD. The control of the VFDs can be (1) centralized using some centralized software controller communicating to the VFDs over the packet network, and/or (2) distributed, in which case VFDs can peer with each other over the packet network, to communicate control state.

    摘要： An apparatus comprises an energy transfer device that operates one or more input switches of an input side of an electrical isolation device to transfer energy through the isolation device to an output side of the electrical isolation device for activating a switch. The apparatus comprises a voltage conversion device that converts the energy from an input voltage of the input side to an output voltage to control the switch when the energy transfer is active. The apparatus comprises a passive turn off device that passively deactivates the switch when the energy transfer is inactive. The passive turn off device is disabled from deactivating the switch when the energy transfer is active.

    摘要： Systems and methods of use relate to a circuit that is designed to detect the state of two control signals, wherein one control signal indicates an ON state for the gate driver and the other control signal indicates an OFF state for the gate driver. The circuit responds to each of the control signals by controlling the gate driver so that it drives an output either high or low. The circuit can also be configured to control the gate driver so that it to drives the output (either high or low) when neither control signal is present.
