    • In a multiphase electrical power assignment, a processor: receives instructions to connect a bi-directional power device to a multiphase premise power source; determines that the power device is to be coupled to a target phase's phase connection; confirms that the power device is not coupled to any phase connections; and couples the power device to the phase connection, where the power device's power signal is synchronized with the phase connection's power signal. When the power device is in a connected state, the processor: issues a command to place each phase connection switch in an open state; in response to confirming that the phase connection switches are in the open state, issues commands to the power device so that a power signal of the power device will be synchronized with the target phase; and closes the phase connection switch corresponding to the target phase.

    • An oscillator circuit and system are provided having a peak detector that can determine a peak voltage value from the oscillator. The peak voltage value can then be compared against a predetermined voltage value by a controller coupled to the peak detector. The comparison value is then used to change a bias signal if the peak voltage value is dissimilar from the predetermined voltage value. A variable capacitor or varactor can be formed from a transistor and is coupled to the oscillator for receiving the bias signal upon a varactor bias node. The bias signal is used to regulate the capacitance within the varactor as applied to the oscillator nodes. Another controller can also be coupled to the peak detector to produce a second bias signal if the peak voltage is dissimilar from a second predetermined voltage value. The second bias signal can then be forwarded into an amplifier having a variable gain to regulate the gain applied to the oscillator. The combination of a varactor and variable gain amplifier regulate the negative resistance applied to the resonating circuit during startup and steady state operations to ensure a relatively fast startup, and to maintain optimal loading and accurate steady state amplitude after startup has completed.

    • An RF generator has an analog feedback circuit in combination with a digital levelling assist circuit to compensate for non-linearities in the power metering circuit that measures the RF output energy. The digital leveling assist circuit has a digitizer with inputs coupled to receive the measured power voltage supplied from the power metering circuit and a power demand voltage. The digitizer has outputs that provide digital representations of the measured power voltage and the power demand voltage to a digital control element that derives a digital correction factor based on these digital representations. A d/a converter coupled to the digital control element provides a correction voltage corresponding to this digital correction factor, and this is furnished to a summing circuit that combines the correction voltage with the power demand voltage and with a control voltage that is supplied by the analog feedback circuit. The leveling assist circuit increases the accuracy of control of the RF output power with respect to the power demand voltage, without sacrificing the speed of the analog feedback circuit.
