摘要： A tap-switching circuit for automatically controlling the output voltage of a multi-tap transformer in response to a varying input line voltage and/or system load current demand, includes voltage sensing circuitry in parallel with both the transformer voltage outputs and a voltage comparator for sensing changes in the system load demand requirements. A voltage reference is provided for automatically generating a pre-selected voltage reference level signal for the line and/or system load requirements. Voltage comparison circuitry is operatively connected with the voltage sensing circuitry for generating an enable signal whenever the input line voltage and/or system load current demand requirements sensed by the voltage sensing circuitry falls below the pre-selected voltage reference level signal. A switching circuit is operatively connected to the voltage comparison circuitry, a linear regulator and to at least two taps of the multi-tap transformer for connecting the higher voltage tap to supply a pre-regulator voltage to the linear regulator whenever the enable signal is present, and for disconnecting the higher voltage tap from supplying its pre-regulator output voltage whenever the enable signal is absent.

摘要： AC isolation apparatus, such as is provided by an AC isolation capacitor disposed between unexposed and exposed portions of the chassis of a charging system or an electric vehicle. The AC isolation apparatus or capacitor provides a high impedance at 50/60 Hertz between the electric vehicle and the charging system, thus isolating their respective chassis grounds.
