For those skilled in the art, the specific meaning of the above terms in the embodiments of this utility model can be understood according to the specific circumstances.

[0021] This utility model embodiment provides a power supply with an airborne rectification and correction module, including an input filtering module, a surge suppression module, a PFC rectification and correction module, and an output filtering module; the input terminal of the input filtering module receives a 115Vac voltage, the output terminal of the input filtering module is connected to the input terminal of the surge suppression module, the output terminal of the surge suppression module is connected to the input terminal of the PFC rectification and correction module, the output terminal of the PFC rectification and correction module is connected to the output filtering module, and the output filtering module can output a 260Vdc voltage.

[0022] In the embodiments of this application, such as Figure 1-3As shown, the input filtering module includes a common-mode inductor Z1, capacitors CY1, CY2, CY3, and CY4. The first and fourth terminals of the common-mode inductor Z1 are connected in parallel to the input terminal of the surge suppression module, and a 115Vac voltage is applied to the second and third terminals of the common-mode inductor Z1. One terminal of capacitor CY1 is connected to the third terminal of the common-mode inductor Z1, and the other terminal of capacitor CY1 is grounded.

One terminal of capacitor CY4 is connected to the first terminal of the common-mode inductor Z1, and the other terminal of capacitor CY4 is grounded.

[0023] For example, the input filtering module is a low-pass filter composed of inductors and capacitors, which allows low-frequency input signals to pass through smoothly while suppressing high-frequency interference.

[0024] For example, the input filtering module mainly uses first-order common-mode and first-order differential-mode noise suppression. The common-mode inductor Z1 forms a common-mode suppression filter network with capacitors CY1, CY2, CY3, and CY4, thereby suppressing common-mode interference.

[0025] In the embodiments of this application, such as Figure 1-3 As shown, the input filtering module also includes differential mode inductors L1 and L2, capacitors CX1 and CX2; one end of differential mode inductor L1 is connected to the first end of common mode inductor Z1, and the other end of differential mode inductor L1 is connected to the input terminal of the surge suppression module; one end of differential mode inductor L2 is connected to the fourth end of common mode inductor Z1, and the other end of differential mode inductor L2 is connected to the input terminal of the surge suppression module; one end of capacitor CX1 is connected to the second end of common mode inductor Z1, and the other end of capacitor CX1 is connected to the third end of common mode inductor Z1; one end of capacitor CX2 is connected between differential mode inductor L1 and the input terminal of the surge suppression module, and the other end of capacitor CX2 is connected between differential mode inductor L2 and the input terminal of the surge suppression module.

[0026] For example, capacitor CX1 is connected in parallel across the AC input signal, and differential mode inductors L1 and L2, together with capacitor CX2, form a double L-type filter network, which can suppress differential mode interference.

[0027] In the embodiments of this application, such as Figure 1-3As shown, the surge suppression module includes a bidirectional transient voltage suppressor V1, a bidirectional transient voltage suppressor V2, resistors R1, R2, R3, and R4; one end of the bidirectional transient voltage suppressor V1 is connected to the differential mode inductor L1, and the other end of the bidirectional transient voltage suppressor V1 is connected to one end of the bidirectional transient voltage suppressor V2, and the other end of the bidirectional transient voltage suppressor V2 is connected to the differential mode inductor L2; one end of the resistor R1 is connected to the capacitor CX2, and the other end of the resistor R1 is connected to the differential mode inductor L2; resistors R2, R3, and R4 are connected in series and then in parallel across the capacitor CX2 and resistor R1.

[0028] For example, bidirectional transient voltage suppressor V1 and bidirectional transient voltage suppressor V2 are connected in parallel at the front end of the PFC rectifier module. They can suppress instantaneous voltage spikes and absorb instantaneous large currents, thereby effectively preventing the downstream PFC rectifier module from being subjected to overvoltage surges.

[0029] For example, when the power supply circuit is subjected to an overvoltage surge, resistor R1 can absorb the surge voltage, thereby preventing damage to the components.

[0030] In the embodiments of this application, such as Figure 1-3 As shown, the surge suppression module also includes a varistor MOV1; the varistor MOV1 is connected in parallel across the capacitor CX1.

[0031] For example, the varistor MOV1 is an input surge voltage suppression device that can suppress and absorb transient peak surge voltages from the power grid, thereby ensuring that the subsequent circuits operate within a safe voltage range and protecting them from damage.

[0033] For example, the output filtering module consists of capacitors. Capacitor C1 is an energy storage capacitor that can ensure the stability of the output voltage of the PFC rectification and correction module; capacitor C2 can reduce output ripple noise; capacitor CX3 can filter out high-frequency voltage interference, thereby meeting the requirements of the load side and ensuring the reliable operation of the load circuit.

[0034] In the embodiments of this application, such as Figure 1-3 As shown, an output protection module is also provided between the PFC rectification and correction module and the output filtering module; the protection module includes MOSFETs Q1 and Q2, resistors R5, R6, and R10, and capacitors C3, C4, and C5; the drain of MOSFET Q1 is connected to the AUX terminal of chip AW1, the source of MOSFET Q1 is connected to the -VOUT terminal of chip AW1, and the gate of MOSFET Q1 is connected to the / LD_EN terminal of chip AW1; the drain of MOSFET Q2 is connected to capacitor C2, the source of MOSFET Q2 is connected to the -VOUT terminal of chip AW1, and the gate of MOSFET Q2 is connected to the chip AW1. Connect the AUX terminal of chip AW1; connect one end of resistor R5 to the AUX terminal of chip AW1, and the other end of resistor R5 to the / LD_EN terminal of chip AW1; connect resistor R6 between the drain of MOSFET Q1 and the AUX terminal of chip AW1; connect resistor R10 and capacitor C5 in series across the source and drain of MOSFET Q2; connect one end of capacitor C3 to the -VOUT terminal of chip AW1, and the other end of capacitor C3 to the / LD_EN terminal of chip AW1; connect one end of capacitor C4 to the drain of MOSFET Q1, and the other end of capacitor C4 to the source of MOSFET Q2.

[0035] For example, by controlling the load, the / LD_EN terminal of chip AW1 can be turned off, thereby protecting the downstream circuit. When the module is working normally, the / LD_EN terminal of chip AW1 is in a conducting state to ground, MOSFET Q2 is turned on, and the power supply circuit starts according to the startup process; when the downstream circuit has faults such as overvoltage or short circuit, the internal Boost circuit of the PFC rectification correction module is turned off, the / LD_EN terminal of chip AW1 is in a high-impedance state, and the AUX terminal of chip AW1 pulls up the gate voltage of MOSFET Q1 through resistor R5, thereby turning on MOSFET Q1, turning off the downstream circuit, and the current-limiting resistor R5 and resistor R6 protect MOSFET Q1.

[0036] In the embodiments of this application, such as Figure 1-3 As shown, the output protection module also includes resistors R7, R8, and R9; one end of resistor R7 is connected between resistor R6 and the drain of MOSFET Q1, and the other end of resistor R7 is connected between capacitor C4 and the gate of MOSFET Q1; resistor R8 is connected in parallel across capacitor C4; and resistor R9 is connected in parallel across capacitor C3.

[0037] For example, resistors R7, R8, and R9 can protect MOSFET Q1 from the impact of the power-on voltage.

[0038] In the embodiments of this application, such as Figure 1-3As shown, the output protection module also includes a thermistor NTC; a thermistor NTC is also connected between the drain of MOSFET Q2 and capacitor C2.

[0039] For example, an NTC thermistor can protect the capacitors in the downstream load circuit from the impact of output surge current.

[0040] In the embodiments of this application, such as Figure 1-3 As shown, fuse F1 is located at the input terminal of the input filter module.

[0041] For example, when a circuit fault occurs and there is an overcurrent, the fuse F1 blows, thereby disconnecting the circuit from the power grid. The fuse F1 serves as input overcurrent protection.

[0042] For example, the power supply of this application can realize AC / DC conversion, and can convert single-phase 115V AC power into 260V DC output, with a maximum output power of 700W. Power factor ≥ 0.98, efficiency ≥ 92%.
