实用新型内容Utility Model Content
为了解决变压器利用率低的问题，本申请提供一种全波整流供电电路。In order to solve the problem of low transformer utilization, the present application provides a full-wave rectification power supply circuit.
本申请提供的一种全波整流供电电路采用如下的技术方案：A full-wave rectifier power supply circuit provided in this application adopts the following technical solution:
一种全波整流供电电路，包括第一二极管、放电模块、传输模块和整流模块，所述第一二极管的输入端连接电源的正极，所述第一二极管的输出端连接所述放电模块的一端，所述放电模块的另一端连接所述传输模块的输入端，所述整流模块包括第二二极管、第三二极管和第二电感，所述第二二极管的输入端连接所述传输模块的第一输出端，所述第二二极管的输出端连接所述第二电感的一端，所述第二电感的另一端用于连接负载电阻的一端，所述第三二极管的输入端连接所述传输模块的第二输出端，所述第三二极管的输出端与所述第二二极管的输出端连接，所述负载电阻的另一端与所述传输模块连接。A full-wave rectifier power supply circuit comprises a first diode, a discharge module, a transmission module and a rectifier module, wherein the input end of the first diode is connected to the positive electrode of a power supply, the output end of the first diode is connected to one end of the discharge module, and the other end of the discharge module is connected to the input end of the transmission module; the rectifier module comprises a second diode, a third diode and a second inductor, the input end of the second diode is connected to the first output end of the transmission module, the output end of the second diode is connected to one end of the second inductor, and the other end of the second inductor is used to connect to one end of a load resistor, the input end of the third diode is connected to the second output end of the transmission module, the output end of the third diode is connected to the output end of the second diode, and the other end of the load resistor is connected to the transmission module.
通过采用上述技术方案，交流电的正半周输入第一二极管进行第一次整流，和放电模块形成回路，电能经过传输模块传输至整流模块的第二二极管，进行第二次整流，对负载电阻进行供电，交流电的负半周流入第一二极管，由于第一二极管的单向导通性，此时电路不导通，放电模块将电能经传输模块传输给第三二极管，进行第二次整流，从而对负载电阻进行供电，如此，交流电的正半周和负半周均能够通过传输模块将电能传输至整流模块，第二二极管和第三二极管进行整流后为负载电阻使用，提高了传输模块的利用率，也提升了电路电能的利用率。By adopting the above technical solution, the positive half cycle of the alternating current is input to the first diode for the first rectification, and forms a loop with the discharge module. The electric energy is transmitted to the second diode of the rectifier module through the transmission module for the second rectification to supply power to the load resistor. The negative half cycle of the alternating current flows into the first diode. Due to the unidirectional conductivity of the first diode, the circuit is not conductive at this time. The discharge module transmits the electric energy to the third diode through the transmission module for the second rectification, thereby supplying power to the load resistor. In this way, both the positive half cycle and the negative half cycle of the alternating current can transmit the electric energy to the rectifier module through the transmission module. The second diode and the third diode are used for the load resistor after rectification, thereby improving the utilization rate of the transmission module and the utilization rate of the circuit electric energy.
优选的，所述放电模块包括第一电感、电容和开关管，所述第一电感的一端连接所述第一二极管的输出端，所述电容的一端连接所述第一电感的另一端，所述电容的另一端连接所述传输模块的第一输入端，所述开关管的一端连接所述第一电感与所述电容的连接节点，所述开关管的另一端连接所述传输模块的第二输入端和电源的负极。Preferably, the discharge module includes a first inductor, a capacitor and a switching tube, one end of the first inductor is connected to the output end of the first diode, one end of the capacitor is connected to the other end of the first inductor, the other end of the capacitor is connected to the first input end of the transmission module, one end of the switching tube is connected to the connection node between the first inductor and the capacitor, and the other end of the switching tube is connected to the second input end of the transmission module and the negative electrode of the power supply.
通过采用上述技术方案，当输入为交流电的负半周时，开关管断开，电容和传输模块构成回路，电容将储存的电能释放出来，释放的电能经变压器的原边传递到变压器的副边，再进行使用。By adopting the above technical solution, when the input is the negative half cycle of the alternating current, the switch tube is disconnected, the capacitor and the transmission module form a loop, the capacitor releases the stored electric energy, and the released electric energy is transmitted to the secondary side of the transformer through the primary side of the transformer and then used.
优选的，所述传输模块为变压器，所述变压器的匝数比为1:1，所述变压器的第一输入端连接所述电容的一端，第二输入端连接所述开关管的一端和电源的负极，所述变压器的第一输出端连接所述第二二极管的输入端，所述变压器的第二输出端连接所述第三二极管的输入端，故所述整流模块的输出端和所述负载电阻一端连接，所述负载电阻的另一端和所述变压器的副边连接，与副边相连的连接点可以改变，从而可以根据不同负载的需要，调整所述变压器副边的匝数比值。Preferably, the transmission module is a transformer, and the turns ratio of the transformer is 1:1. The first input end of the transformer is connected to one end of the capacitor, the second input end is connected to one end of the switch tube and the negative electrode of the power supply, the first output end of the transformer is connected to the input end of the second diode, and the second output end of the transformer is connected to the input end of the third diode. Therefore, the output end of the rectifier module is connected to one end of the load resistor, and the other end of the load resistor is connected to the secondary side of the transformer. The connection point connected to the secondary side can be changed, so that the turns ratio of the secondary side of the transformer can be adjusted according to the needs of different loads.
通过采用上述技术方案，传输模块使用变压器，既实现了电能的传输，也将变压器之前的电路和之后的电路进行隔离，利于电能使用的稳定性。By adopting the above technical solution, the transmission module uses a transformer, which not only realizes the transmission of electric energy, but also isolates the circuit before the transformer and the circuit after the transformer, which is beneficial to the stability of electric energy use.
综上所述，本申请包括以下至少一种有益技术效果：In summary, the present application includes at least one of the following beneficial technical effects:
1.增加了第三二极管和第二电感，使输入交流电的负半周时的电能也能够被利用，提升了变压器的利用率和电路电能的利用率。1. The third diode and the second inductor are added so that the electric energy during the negative half cycle of the input AC power can also be utilized, thereby improving the utilization rate of the transformer and the utilization rate of the circuit electric energy.
