Method for a current mode buck-boost converter |
摘要 |
A current mode control buck-boost converter with improved performance utilizes separate buck and boost pulses. The buck-boost converter utilizes a buck/boost decision method with continuous control voltage for buck and boost mode, therefore eliminating transients in the control loop between operation modes and preventing voltage overshoots. If switching in Boost mode and the buck duty cycle is smaller than a set duty cycle, then in the next cycle Buck mode switching will occur. It is possible to track a Buck comparator output and the related duty cycle during Boost mode operation. Thus a mode change decision will only be dependent on a single input. A control loop will incorporate a single loop filter and error amplifier, wherein control voltages for Buck comparator and Boost comparator will be related. |
