Embodiment Construction

[0015] like figure 1 As shown, the three-phase ABC voltage of the wind power generator of the present invention is rectified by diodes to obtain the DC bus voltage Vbus. DC output voltage Vout, the four-inductance DC-DC converter can achieve a stable output voltage, and can adjust the impact of the fluctuation of the output voltage of the wind turbine, and flexibly adjust the DC bus voltage to avoid fluctuations in the output voltage .

[0016] Its circuit topology is specifically that the three-phase ABC voltage of the wind turbine is connected to the full-wave rectification of the diode to obtain the DC bus voltage Vbus, the positive end of the DC bus voltage Vbus is connected to one end of the start switch S, and the other end of the start switch S is connected to the switch tube S1 One end and one end of the capacitor C1, the other end of the switch tube S1 is connected to the cathode of the diode D1 and one end of the inductor L2, the anode of the diode D1 is connected t...

Abstract

The invention discloses a charging voltage stabilization module of a communication power supply. A three-phase voltage output from a draught fan is rectified by the module and then passes through a four-inductor DC-DC converter to achieve stable-voltage output, the voltage stabilization module can be used for performing duty ratio control on a switch tube according to a set output voltage value and a feedback output voltage value, so that the output voltage can rapidly flow the output voltage setting value, the voltage fluctuation of a DC bus also can be effectively adapted to achieve stable-voltage output; and by integrally designing the voltage stabilization module, the pluggable design is conveniently achieved, a series of wiring problems of maintenance, after-sale and installation aresolved, and the product maintenance is facilitated.

Description

technical field [0001] The invention relates to a voltage stabilizing module, in particular to a communication power supply charging and stabilizing module. Background technique [0002] At present, the power supply of the communication equipment room is mainly from the mains power supply of the national grid. The biggest advantage of the mains power supply is that it is stable and reliable, and it is also the optimal power supply scheme for communications. However, there are also some areas without electricity and mountainous areas where it is inconvenient to use mains power when setting up communication equipment, or the cost of using mains power is very high. Usually, new energy is used for power supply to solve the power supply problem. [0003] In the existing new energy power supply methods, most of them are photovoltaic power supply. As an important link in communication power supply, photovoltaic power supply is indeed an indispensable link. However, if only photovo...
