Current detection method, device terminal, and readable storage medium

Abstract

The invention relates to a current detecting method, a device terminal, and a readable storage medium. The current detecting method comprises the steps thatthe switching state and thecurrent initial estimated value of each loop are acquired, timing is started,a bus estimated current is determinedaccording to the switching state and the current initial estimated value of each loop, the bus currentestimation difference between the bus real-time current and the bus estimated current is calculated,when one or more are conducted in each loop, a convergence variable is determined according to the total number of conducted loops, the bus estimated current, and the bus current estimation difference, a current estimated value of current corresponding to each conducted loop is calculated accordingto the convergence variable, and whether the accumulated timing time reaches a preset time range or not is determined; if yes, whether the bus current estimation difference belongs to the preset difference range or not is further determined; and if yes, the current estimated value of the current corresponding to each conducted loop is used as the current detection value corresponding to each loop.According to the current detection method, the cost of current detection is lowered.

Description

technical field [0001] The invention relates to the field of electric power regulation, in particular to a power regulating method, a device terminal and a readable storage medium. Background technique [0002] The current current regulator needs to control the corresponding output current or output power, which requires current detection for each output loop, and then needs to add current detection devices in each loop. However, the more detection devices, the detection unit will be too large. Huge, the higher the cost, and the analog-to-digital conversion control channel interface of the conventional control CPU processor is limited, and the scalability of the entire circuit is not strong. Contents of the invention [0003] In view of the above problems, the present invention proposes a current detection method, a device terminal and a readable storage medium. By adding a current detection unit on the circuit bus side, the real-time current of the bus and the switching s...
