Problems solved by technology

However, after a period of time, the cells in such devices tend to degrade and become less efficient
For non-adaptive regulators, this deviation results in significant wastage of energy and reduces device lifetime

Abstract

The invention provides a voltage regulator circuit including: a comparator configured to have a first input coupled to an output voltage of the voltage regulator circuit; a second input coupled to a reference voltage and an output signal; a first transistor; a second transistor, a drain of the first transistor connected to a drain of the second transistor; an inductor connected to the drain of the first transistor and the drain of the second transistor; a capacitor and a resistor connected in parallel, between the output node and a source of the second transistor; a peak-current detector unit configured to detect peak current in the inductor; a zero-crossing detector unit configured to detect a zero-crossing current in the inductor; and a control unit configured to receive a plurality of input signals including at least an input voltage and a clock signal.

Description

technical field [0001] The present invention generally relates to the field of electronics, and more specifically, to a voltage stabilizing circuit and a voltage stabilizing method. Background technique [0002] Voltage regulators are designed to maintain a constant voltage level. Regulators can be a simple "feedforward" design or can include a negative feedback control loop. Voltage regulators can use electromechanical or electronic components and, depending on the design, can be used to regulate one or more AC or DC voltages. Electronic voltage regulators are found in devices such as computer power supplies, where they stabilize the DC voltage used by processors and other components. In automotive alternator and central power station generator plants, voltage regulators control the output of the plant. In power distribution systems, voltage stabilizers can be installed in substations or along distribution lines so that all consumers receive a stable voltage regardless o...
