摘要: A cascaded buck+boost inrush limiter is claimed where the buck converter is only allowed to switch for very short times and stays turned on, or off, during steady state operation. The inrush limiter has a control system having a digital controller and an analog comparator for controlling the buck and boost converters. The system utilizes a single loop current feedback.

摘要: A power factor correction voltage controller is disclosed. In one embodiment, the controller has a linear PI compensator, a moving average filter, a non-linear error circuit, a hysteretic peak control, and an output power feedforward. The power factor correction voltage controller provides regulation of maximum and minimum voltage values but without allowing large periodic fluctuations in the input power/current.

摘要: A high voltage AC measurement method and circuit is disclosed to measure with zero offset and mirrored distortion based on hybrid chopping and fully differential signal path. There is a scheme with hybrid chopping and dual mixed signal paths. It applies high frequency chopping to the voltage measurement signal before the low-voltage signal conditioning, then samples and converts it to digital with two simultaneous ADCs, and finally demodulate the chopped signal by software. This technique not only reduces DC errors and drift but also cancels the distortion asymmetry caused by ADC non-linearity. The resultant DC accuracy and resolution can be significantly smaller than 1 LSB.
