Abstract

The invention provides a wind power generator soft braking circuit. The wind power generator soft braking circuit is characterized by comprising thermal resistors CR1 to CR3, MOS tubes Q1 to Q3, resistors R1 to R8, an MOS drive circuit and a micro processor U1. The single chip processor outputs control signals of the MOS tubes, after the MOS tubes are powered on, the temperature of the thermal resistors raises, the resistance is decreased gradually and approaches zero, a turbine is in short circuit to be in a braking state, and the circuit is simple, reliable and easy to realize.

Description

technical field [0001] The present invention relates to the technical field of controllers, and more specifically, to a soft braking circuit of a wind power generator. Background technique [0002] With the development of the economy, the human demand for energy is increasing, the traditional energy reserves are increasingly depleted, and the harm caused by the extensive use of traditional fuels to the human living environment is becoming more and more prominent. The development and utilization of renewable energy has become an important and urgent issue at present. Among the clean energy, wind energy and solar energy are the energy sources with the most development value, among which wind energy is a device that uses wind power to generate electricity. The power generation system of wind power generation is mainly composed of wind power generator, wind power generation controller, storage battery and so on. The wind power generator braking circuit is the main component of ...
