摘要:
Systems and methods may provide for a transient response apparatus that includes a single stage conversion module having a power input, a power output, and a control input, and a compensation module including a feedback input. The compensation module may be coupled to the power input, the power output and the control input of the single stage conversion module. Additionally, a feedback module may be coupled to the power output of the single stage conversion module and the feedback input of the compensation module. In one example, the feedback module includes a loop controller having a plurality of programmable inputs and an error output, and a modulus unit coupled to the error output of the loop controller and the feedback input of the compensation module.
摘要:
Methods and apparatus relating to a unified control scheme for non-inverting high-efficiency buck-boost power converters are described. In an embodiment, compensator logic causes a buck-boost power converter to provide an output voltage with a higher voltage level than an input voltage in a boost operational mode of the buck-boost power converter and to provide the output voltage with a lower voltage level than the input voltage in a buck operational mode of the buck-boost power converter. The compensator logic provides N+1 bits to Pulse Width Modulation (PWM) generator logic to cause the buck-boost power converter to provide the output voltage. One of the N+1 bits indicates whether the buck-boost power converter is to provide the buck operation or the boost operation. Other embodiments are also disclosed and claimed.
