Abstract

A coaxial AC-DC brushless generator characterizes in designing AC-DC two sets of windings distributed in a single pivot and designing a brushless exciter on the axis. This invention can provide AC supply of a certain frequency and DC supply with small DC voltage ripple values at the same time to realize brushless and eliminate commutators and brushes.

Description

technical field [0001] The invention relates to a coaxial AC / DC brushless generator. Background technique [0002] The AC power can be provided by a single AC generator, and the DC power can be provided by a single DC generator. To provide DC power for AC power at the same time, only one AC generator and one DC generator can provide it. The traditional DC generator is equipped with a commutator and brushes. This kind of generator has a commutator structure, sparks are generated during operation, radio interference is large, sliding is easy to wear, maintenance and repair are difficult, the excitation current is large, and the excitation system The controller is large and complex, and it is difficult to realize automatic control. Another way to obtain DC power is to use an ordinary alternator, step down the AC voltage, and then rectify it. This requires a step-down transformer, and the DC voltage ripple value is relatively large. Contents of the invention [0003] The pu...
