Embodiment Construction
[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0046] When the number of switch state groups manually edited by the user reaches a certain level, it is obviously tedious and error-prone to set the on-delay time and off-delay time of each group in turn. In order to solve the problem of setting on-delay and off-delay, the embodiment of the present invention proposes a method for automatical...

The invention provides a power supply capable of time-delay switching on / off and a working method of the power supply. The power supply comprises an automatic switching control device. The automatic switching control device comprises a switching state generation unit, a time sequence generation unit, a timing unit and an output state control unit, wherein the switching state generation unit is used for generating a switching state table which comprises a switching sequence composed of multiple on states and multiple off states; according to time-delay parameters set by a user, the time sequence generation unit automatically generates a time sequence table which comprises delayed time durations corresponding different on / off states; the timing unit generates interruption periodically; and the output state control unit switches on / off states of the power supply according to the interruption generated by the timing unit, the switching state table and the time sequence table. The power supply can automatically accurately control on / off of time delay.
Description
technical field [0001] The invention relates to the field of general electronic measurement and testing, in particular to a power supply with switch delay function and its working method. Background technique [0002] As an indispensable tool in electronic design, linear DC power supply can work not only as a power supply, but also as a measuring device. It is widely used in various fields such as laboratories, scientific research units, and industries. With the digitalization of electronic devices becoming more and more common, the original linear analog power supply will gradually be replaced by digital power supply. Digital power supply has the characteristics of good scalability, lower cost, simpler circuit, easy mass production, and stable performance. Usually have voltage, current continuously adjustable function, and output switch function. [0003] The control of the output switch is divided into two categories. One is to directly disconnect the connection physicall...
