摘要： Some embodiments of the present invention provide a system for charging a series battery, wherein the series battery is comprised of a set of banks which are connected in series, so that the same charging current passes through each bank. During the charging process, the system measures a voltage across each bank in the set of banks. The system then compares the measured voltage with a target voltage for each bank, and adjusts the charging process based on results of the comparisons between the measured voltage and the target voltage.

摘要： The disclosed embodiments provide a system which starts up and shuts down a resonant oscillator circuit. During the start up process, a driving circuit uses a first clock signal to control a first phase output of the resonant oscillator circuit. At the same time, the driving circuit uses a second clock signal to control a second phase output of the resonant oscillator circuit, wherein the first and second clock signals have opposite phases. While the first and second phase outputs are being controlled, the system ramps up an input voltage, which is used to power the resonant oscillator circuit, wherein the ramping takes place across multiple initial oscillation periods. During the shut down process, the system shuts down the resonant oscillator circuit by ramping down the input voltage. After the input voltage has been ramped down, the system clamps the first and second phase outputs to a fixed voltage.
