Abstract:
The hysteresis control combined with PWM control non-inverting buck-boost was proposed to improve the light load efficiency and power density. The constant inductor current control(CICC)was established to mitigate the dependence on the external components and device variation and make smooth transition between hysteresis control loop and pulse width modulation(PWM)control loop. The small signal model was deduced for the buck and boost operation mode. The inductor current slope control(ICSC)was proposed to implement the automatic mode transition between buck and boost mode in one switching cycle. The results show that the converter prototype has good dynamic response capability, achieving 94% efficiency and 95% peak efficiency at full 10 A load current.
