Buck-Boost Converter Mode Transition Control for Stable Output Voltage

The patent applies preliminary action by detecting peak current events and starting timers in advance to predict when mode transitions should occur. The control unit prepares for mode transitions by monitoring the timer signals and clock signals, ensuring that transitions happen at optimal moments (at peak current events) to minimize output voltage disturbances. This proactive approach allows the system to anticipate and prepare for mode changes before they fully occur.

The patent implements feedback mechanisms by continuously monitoring the output voltage, detecting peak current events, and comparing timer signals with clock signals. The control unit uses this feedback information to determine whether to transition between operation modes and to adjust the duty cycle accordingly. The feedback loop ensures that mode transitions are based on actual system conditions, preventing premature or inappropriate transitions that could cause instability.

The control unit performs preliminary actions by detecting peak current events and starting timers before mode transitions occur. This allows the system to prepare duty cycle adjustments in advance, ensuring that transitions happen smoothly at predetermined moments rather than abruptly. The timer mechanism ensures that duty cycle changes are coordinated with the switching cycle, preventing discontinuities in the error signal.

The patent applies dynamics by making the duty cycle adjustable and variable based on operating conditions. The control unit dynamically modifies the duty cycle during operation, transitioning between fixed duty cycle values as needed when changing between operation modes. This dynamic adjustment allows the system to adapt to changing battery voltage levels while maintaining continuous and stable error signals throughout the transition process.
