Aircraft ground miniaturization power supply suitable for multiple power supply modes

Abstract

The invention provides an aircraft ground miniaturization power supply suitable for multiple power supply modes. The aircraft ground miniaturization power supply comprises a three-phase intermediate-frequency static variable power supply circuit, a DC static conversion power supply circuit, a power network voltage sampling circuit, a voltage interval judgment circuit, a serial and parallel connection control circuit and a primary-side winding serial and parallel connection switching circuit. The aircraft ground miniaturization power supply capable of separately providing an AC power supply or a DC power supply and also capable of simultaneously providing the AC power supply and the DC power supply completely covers active-service aircrafts, serves several purposes, saves investment and is convenient to use. Commercial AC power supplies of various countries around the world or AC generators can be adopted to provide power, and self power supply of the active-service aircrafts at home and abroad can be met; and a battery pack can also be adopted to provide power, and field or military applications are convenient. A circuit topological structure is simple, the whole body of equipment is miniaturized, vehicle type housing with rollers is designed, on-board engine-driven transferring is convenient, and the aircraft ground miniaturization power supply has great application value in military.

Description

technical field [0001] The invention relates to the field of aviation ground power supplies, in particular to a miniaturized aircraft ground power supply adaptable to various power supply modes. Background technique [0002] In the aviation industry, various ground support equipment provide power and compressed air to aircraft. Aircraft can be powered by using aircraft generators, however, because generating electricity with aircraft generators will consume fuel, and more importantly, consider the safety of ground personnel, so generally the aircraft generators are disabled at any time when the aircraft is started on the ground. [0003] In this way, when the aircraft is powered on, inspected or started on the ground, it needs external power supply, and radar, missile and other equipment also need to provide ground power supply protection. [0004] However, not all aircraft are designed to have power sources with the same characteristics. For example, some aircraft use AC ...
