Description

Technical Field

Background

At present, production and life are not powered on, and the main source of electricity is to meet the demand through a generator for power generation. Generator types are divided into ac and dc, but alternators are the mainstream of demand.

The efficiency-enhancing and energy-saving output circuit of the alternating-current generator makes subversive change and optimization on the power supply circuit, so that the generator does not need to increase extra power and torque when supplying power to a load, namely the generator is in an idle state like the generator when driving the load, and the problem of effectively reducing the energy consumption of the generator for generating power is solved, and the power generation efficiency of the generator is improved.
