Wind power generation device capable of low speed and high power

Abstract

A wind power generating device capable of low rotation speed and high electric energy comprises a wind power generating unit and a circuit unit. The circuit unit includes a plurality of circuit modules electrically connected to the wind power generation unit, and each circuit module includes a rectifier circuit, a voltage conversion circuit, a switch circuit, an output interface, and a control circuit. The rectifier circuit receives the power of the wind power generation unit and outputs an input voltage and an input current. The voltage conversion circuit receives the input voltage and the input current and outputs an output voltage and an output current. The switch circuit is electrically connected between the voltage conversion circuit and a ground terminal, and is controlled to be switched to conduction or non-conduction. The control circuit adjusts the conduction and non-conduction time of the switch circuit according to an input power and an output power, so as to obtain the optimized input power and the output power, so as to solve the loss of power generation efficiency and achieve the optimization of the overall power generation efficiency .

Problems solved by technology

[0006] However, in practical applications, due to individual differences between each coil 113, the power generation efficiency and output phase of each coil 113 are not consistent, resulting in that when the output of the circuit module 121 is used in parallel, it will be caused by phase inconsistency. There are cases of offset and loss, resulting in a decrease in power generation efficiency
