[Prior Art] ΜΑ p 丨q seeks the AC-to-DC charge group 10 sorrow, belonging to the AC voltage 1% 1], · spring voltage and neutral voltage (neutral), and a bridge rectifier 103 is rectified into a positive voltage and a constant current is applied to a storage capacitor 403. The end points of the energy storage electrode 401 1 0 are respectively 405/406, and the voltage values of the two ends to ground can be expressed as V2+/v2_, via a transformer pressure crying = connected to the output of the charger 1G 'reconnected to test common mode noise _ (needle picking 02) 'This shows the charger 1Q as the instrument to be tested (eut) for common mode noise (common_mode n〇ise) Test connection. - Common mode noise test. The general specification can be expressed as -10 million (Mega) ohm resistor 102a in parallel - 8 pico Farad capacitors 102b, v3 is the AC voltage value measured by the common-mode noise test probe 1〇2, which is the common mode noise. For further review by the reviewer, Figure 2 shows the charger 1 for common mode noise. A further simplified illustration of the connection of the instrument under test, in Figure 2, 405/4 of the storage capacitor 403 06 Establishing a rectified DC voltage, the bridge rectifier 103 (there is generally no further description of the four diodes) is further simplified to two diodes 2〇1 connected to the line end 401 and 202, while the other two diodes connected to the t-terminus 402 are omitted here (because they are blocked by the voltage across the storage capacitor 403 and therefore do not conduct), the transformer is further simplified to 〆 equivalent to, for example, approximately 45 pico (p 1 co) farad capacitor 105. 3/11 M413276 Because the DC voltage across the storage capacitor is approximately equal to the AC portion of the time, and no charging current flows to =ηΤ Λ 'to help understand 'in the figure The waveform of 3 assumes that the voltage across the storage energy valley 403 is approximately equal to the peak value of the AC voltage vl, so that ',: the charging path (4) of the bridge 1G3 is blocked, and the AC voltage is input. The bridge-type 1Q3 current must flow from the far-end to the common-mode test probe, which is represented by only the resistor. At very low frequencies, the capacitance is negligible. - Figure 3 shows the corresponding waveform of the simplified model of Figure 2, v2, is the derivative of the ground voltage value v2+ and v2_ differential of 405/406 at both ends of the energy storage f 403 'V3 is the common mode arm sound test The voltage value measured by the probe 102, that is, the common vowel. Although v3 is not shown in Figure 3, the capacitor 105 and the resistor purchase end point together form a micro ((10) ferentiatoi) and V3 is the output voltage value of the differentiator, so those skilled in the art can derive v3. The value is proportional to the first derivative v2' of v2. "" ... From the above derivation, the common mode noise is proportional to v2, and v2+/v2~ is driven by vl, and V2 can also be regarded as the derivative of vl. And how to reduce the common mode:! The dullness is what the creation wants to explore. [New content] This: I] is a power rectifier circuit with a low common mode noise (common-mode n〇ise), which includes: a storage capacitor 'f-end and second end Inter-storage--------------------------------------------------------------------------------------------------------------------------------------- Voltage production; m its two rounds in the storage capacitor and the 4/11 line terminal . · The neutral end point and m two (four) combined with the Lai energy capacitor and the common effect is to reduce the Yingxian power rectifier circuit The charger read the steps to understand the characteristics and technical content of the creation, and the detailed description and drawings of the creation, but these statements are used to explain the creation, not the scope of rights to the creation: Mode 4 shows an embodiment of the present invention, which is a common state, a state 40, which comprises a storage capacitor 4〇3, and a first-voltage difference between the agricultural terminal 405 and the second terminal; ^ Rectifier ϋ 404, can be - full bridge with four diodes = = road 'therefore by the line end. Point 401 The neutral terminal 4〇2 receives the line voltage = voltage to convert the line voltage and the neutral voltage difference is the i-two voltage ί ' : the first impedance 407 ' is coupled to the storage capacitor a second impedance of the second impedance, the two ends of which are coupled to the second end of the valley 403 and the neutral end 402; and an equivalent capacitance 1G5 of a power Ai circuit, which may be A simple controller (the power conversion circuit not controlled by the common mode noise from the rectifier circuit is coupled to one of the outputs of the charger 40. /, where the first impedance 407 and the second impedance 408 are stored The voltage across the capacitor 403 is no longer determined solely by the line w, but is simultaneously determined by a function of the line voltage v1 and the neutral voltage, such as the average of the two, wherein the first impedance 407 and the second impedance The impedance value of 408 is the same. 5/11 M413276 Neutral voltage is zero voltage under normal conditions, so the 'wire voltage w and the function of neutral voltage', for example, the average of the two materials is effectively reduced to - half, when energy storage The voltage value v2 to the ground across the capacitor 403 is reduced to the original line voltage vl - half When the signal is driven, the common mode noise is also reduced, as shown in FIG. 5. The first impedance 407 and the second impedance 4〇8 of the raft can use general resistance, capacitance, and inductance devices. The combination of the first impedance 407 and the second impedance 408 and the energy storage electrode β 403 is not limited to the relationship shown in FIG. 4. The signal V2+ shown in FIG. And ν2- is significantly smoother than Figure 3, so its first derivative v2' is also much lower than the derivative v2 of the v2 signal shown in Figure 3. Therefore, the charger shown in this application can achieve the reduction of common mode noise. Figure 6 shows another embodiment of the present invention, which is a low common mode noise rectifying circuit 60, compared with Figure 4, wherein the first impedance 407 and the first impedance 408 in Figure 4 are a first resistor 601. And a second resistor β〇2 is replaced. The rectifier circuit 60 also includes: a line terminal 401; - a neutral terminal 4 〇 2; - a storage capacitor 403; - an AC to DC rectifier 404; the coupling capacitor is omitted here. Figure 7 shows another implementation of the present invention. For example, the whole circuit 70' of a low common mode noise is compared with FIG. 4, wherein the first impedance 407 and the second impedance 408 in FIG. 4 are replaced by a first capacitor 701 and a second capacitor 702. The rectifier circuit 70 also includes: a line terminal 401; a neutral terminal 402; a storage capacitor 403; an AC to DC rectifier 404; the coupling capacitor is omitted here. Since the DC voltage difference across the storage capacitor is substantially constant, the 6/11 M413276 impedance and the second impedance only need to have a sufficiently high DC resistance (for example, a battery), At any end of the energy storage capacitor, the working principle and effect of the creation are not affected. Hereinafter, a related embodiment will be described with reference to Figs. 8 and 9. 8 shows another embodiment of the present invention, which is a low common mode noise rectifying circuit 80. Compared with FIG. 4, the rectifying circuit 80 also includes: a line end point 401; a neutral end point 402; - a storage capacitor 403; - AC to DC rectifier 404; first impedance 407 and second impedance 408. The first resistor 407 and the second impedance 408 are both coupled to the first end of the storage capacitor 々os. It should be noted that the first impedance 407 and the second impedance 4 〇 8 need to have a direct current DC impedance, and the consumption capacitance is omitted here. a low common mode noise
