    Abstract: A battery module for use in a battery system is operable in a bottom mode, a top mode or a middle mode during an enabled state. The battery module includes a battery unit and a battery control circuit. The battery unit which includes at least one battery generates a battery unit voltage between a positive terminal and a negative terminal of the battery unit. The battery control circuit is powered by the battery unit voltage and is configured to control the battery unit. The battery control circuit includes an enable terminal, an upstream input terminal, an upstream output terminal, a downstream input terminal, and a downstream output terminal. When the enable terminal is at an operation enabling level, or when the upstream input terminal is at an upstream enabling level, the battery module enters the enabled state.

    Abstract: A switching controller circuit for controlling a flyback power converter includes: a power transformer, a primary side controller circuit and a secondary side controller circuit. The power transformer is coupled between the input voltage and the output voltage in an isolated manner. The primary side controller circuit controls a primary side switch of the flyback power converter. The secondary side controller circuit generates a synchronous rectification (SR) signal, to control an SR switch of the flyback power converter. The SR signal includes an SR pulse and a soft switching (SS) pulse. The SR pulse controls the SR switch to be ON for an SR period, to achieve synchronous rectification at the secondary side. The SS pulse controls the SR switch to be ON for an SS period, to achieve soft switching of the primary side switch.
