Title: Voltage regulator with piecewise linear loadlines
Inventor: YOUNG CHRIS M
IPC: H02M1/08
Filed: 2020-11-04
Granted: 2022-06-11
Abstract: Apparatus and associated methods relate to providing a piecewise loadline having a number of segments with different slopes and selecting a segment of the piecewise loadline based on an output current of a power supply. In an illustrative example, the piecewise loadline may include a segment that has a negative slope. When the output current is less than a predetermined threshold, the segment with the negative slope may be selected to improve power efficiency. In some embodiments, the piecewise loadline may have several segments with different positive slopes. Different segments may be selected to make the load work in different modes. For example, by selecting an overcurrent loadline, the load (e.g., a processor) may be informed to throttle back its performance. Having a piecewise loadline may allow independent optimization of the loadline resistances, voltage thresholds, and current limits.

Abstract: A method for controlling air conditioner demand response, the method to be implemented using an air-conditioning demand response control system to adjust each temperature of N field spaces, where N is a positive integer and N≥2. The method comprises the following steps. When the air-conditioning response control system receives a demand response request command, it executes a double deep Q network machine learning model to calculate a customer baseline load corresponding to each field space according to a reward function. The air-conditioning response control system further calculates an electricity limit of each field space according to the N customer baseline loads and a total electricity limit. The double deep Q network machine learning model trains an exploratory action based on the N customer baseline loads, the N electricity limits, and N temperature feedback values. The exploratory action is related to finding a maximum reward to achieve a minimum standard of comfort.
