The following is a detailed description of the detailed circuit of the above embodiment, please cooperate with the first and second figures, The AC to DC circuit (1 〇) is mainly composed of a full-wave rectifier (D1 to D4). The charging control circuit (60) includes a pulse width modulation (PWM) circuit (6 1 ), a sensing Circuit (6 2 ) ' - isolated controller (6 3 ) and a switch (6 4 ), wherein: the pulse width modulation (pwm) circuit (6 1 ) is connected to the aforementioned AC to DC circuit (1 0 And the transformer (3 0) - the secondary side (3 1 ) to control the size of the DC power supply to the transformer (3 0) - the secondary side (3 1 ), when the DC power supply is larger, the self-transformer (3 0 The booster power supply of the secondary side (3 2 ) output is larger. In this embodiment, the pulse width modulation circuit 6 1 ) mainly comprises a control IC ( U1 ), the control 1C is connected to the aforementioned AC-DC circuit (10) and the Lu-sub-side (3 1 ) of the transformer (30); the sensing circuit (6 2 ) is Connecting the secondary side (3 2 ) of the transformer (30) to detect the output voltage of the output interface (40). In this embodiment, the sensing circuit (62) mainly includes the first and second Third and fourth resistors (R17) (R14) (R18) (R15), the resistors (R17) (R14) (R18) (R15) are sequentially connected in series, wherein the other end of the first resistor (R17) The transformer (30) is connected to the secondary side (32) and the output interface (40), and the other 6 1323550 of the fourth resistor (RI5) is grounded; the isolated controller (63) is a receiving end ( 6 3 1 ) connecting the aforementioned pulse width modulation circuit (6 i ), and connecting the sensing circuit ( 6 2 ) with a transmitting end (6 3 2 ), in the embodiment, the isolated controller (6) 3) an optical coupler, the equivalent light-emitting diode (PH1A) in the optical coupler is connected to the transmitting end (6 3 2 ) of the sensing circuit (62), and the optical coupling is beneficial.

The pulse width modulation circuit (6丄) detects the equivalent photoelectric crystal in the device (P When H1B) is in the on state, the /width modulation circuit (6 1) will not adjust the DC power supply of the input transformer (3〇) secondary side (3 1 ); when a battery to be charged (5 〇) is connected After the round-out interface (4 〇), 'the power of the battery (50) is insufficient, the voltage of the output interface (4〇) will be lowered, and the voltage of the series node (κ) will be lowered to a low level. When the switch (6 4 ) is turned off and the switch (6 4 ) is turned off, the equivalent light-emitting diode (ΡΗ1Α) in the photocoupler is also turned off without being brightened, so that the equivalent photo-crystal (ΡΗ1Β) in the photocoupler is turned off. At this time, the pulse width modulation circuit (6 1 ) detects that the equivalent photoelectric crystal (ρΗΐΒ) in the optical coupler is in an off state, so that the feeding transformer (3 〇) is added to the secondary side (3 working). The direct power supply size is increased until the voltage of the output interface (40) is increased so that the voltage of the series connection node (K) is sufficient to turn the switch (6 4 ) into conduction, thereby making the equivalent light-emitting diode in the optical coupler (PH1A) is turned on and the equivalent photonic crystal (PH1B) in the driving light combiner is turned on at this time. The degree modulation circuit (61) detects that the equivalent photo-electric crystal (PH1B) in the photocoupler is in a conducting state, so the pulse width modulation circuit (6 1 ) is lowered into the transformer (3 〇). - DC power supply on the secondary side (3 workers). 1323550 The secondary side (3 2 ) is in the ψ φ " 崎 impedance, so it becomes crying f? n, the output voltage of the grazing wheel is transmitted to the output eight products. 0) Line impedance Will consume part of the wheel out of the house, when the surface (4 〇), the house is slightly lower than the self-transformer (battery (50) charging voltage; and the invention 14 ±) primary side (3 2) road #山月月The power output from the compensation circuit (7 n ) ζ ) is connected to the transformer at the negative end (the positive terminal of the diode (D12) of the diode (D12) is equivalently produced by the second-side; owed: (32), It can be used in the two-pole (four) device (30) secondary voltage source 1 negative power source system change 'so when the battery to be charged ("the voltage of the wheel is changed to cause the electric dust of the series node (1) to decrease,: out: face (...Connect:: Radio and TV is willing to lower it again, so that the control source will make the DC power supply of the string more convenient to the transformer (U1) must be controlled to further improve the transformer. 3 billion) di ^) secondary side (31), then because the actual packet loss resistance line, 'the output voltage, whereby compensation (5〇) charge. However, it can be known from the above that the battery can be charged in the pool, and the invention can not only compensate the electric dust charged in the pool, but also can compensate for the electric energy lost by the electric circuit when the compensation is matched with the eight-cell.
