Problems solved by technology

The dynamic performance of other power systems currently being studied is not satisfactory. For example, when the load is suddenly added or unloaded, the dynamic recovery time of the output voltage is greater than 100ms, which is far from meeting the requirements of modern aircraft and other high-tech

Abstract

An instantaneous torque controlled DC starting / electric generation system with electric / electronic converter for cage-type asynchronous dynamo is composed of asynchronous dynamo, power converter, filtering circuit, low-voltage auxiliary powr supply, converter control signal unit, control system based on digital signal processing, A / D converter, AC Hall sensor, DC Hall sensor, and Hall voltage sensor. Its advantages are high dynamic response speed and simple structure.

Description

technical field [0001] The invention relates to a DC power generation system and a control method for a power electronic converter of a cage-type asynchronous motor controlled by instantaneous torque. Background technique [0002] With the high-tech development of aircraft, tanks, warships, ships, etc., a large number of control equipment and precision instruments must adopt modern computer control technology, which puts forward higher and higher requirements for power supplies, not only requiring a substantial increase in power supply capacity, but also requiring High speed, dual functions, high performance, high stability and other performance qualities, such as the requirement that the dynamic recovery time of the output voltage is less than 30ms (U.S. military standard) when the load is suddenly added or unloaded, so as to meet the needs of telex systems and advanced instruments Requirements for uninterrupted power supply, high precision of output power, etc. For this r...
