【Specific embodiment】
Referring to Fig. 1, circuit is opened in the anti-hiccup circuit of Switching Power Supply of photovoltaic system, including power circuitry, driving, is driven and is closed
Deenergizing, Switching Power Supply starts connection circuit.
Power circuitry is made up of R1-R8 and Q1, and, used as energy consumption resistance, Q1 is used as switch control rule for wherein R1-R8；PV+ and PV-
For the input of photovoltaic module, when illumination is weak, Q1 is in opening state, R1-R8 resistance connection circuits, by photovoltaic module voltage clamping
Low pressure.
Circuit is opened in driving, is made up of R9-R12, R17, C1 and ZD2.R9-R12 and R17 constitutes 1 series resistance, resistance
R17 is divider resistance, and C1 is filter capacitor, and ZD2 is voltage-stabiliser tube；PV+ and PV- is the input of photovoltaic module, when having illumination, PV+
There is voltage between PV-, through resistance R17 partial pressures, and voltage stabilizing is carried out by ZD2,1 driving voltage is produced to Q1, force Q1 to lead
It is logical.
Breaking circuit is driven, is made up of R13-R16, R18-R20, C2, Q2 and ZD1.R13-R16 and R19 constitutes 1 series connection
Resistance, R19 is divider resistance, and C2 is filter capacitor, and R18 is current limliting and divider resistance, and ZD1 is voltage-stabiliser tube, and R19 is electric to drive
Resistance；PV+ and PV- is the input of photovoltaic module, when having illumination, there is voltage between PV+ and PV-, through resistance R19 partial pressures, only
When illumination is sufficiently strong, when the voltage of R19 is more than 0.6V, Q2 is forced to turn on, so as to cause the driving voltage of Q1 low, so as to compel
Turn off Q1.On the other hand, once Q1 is turned off, Switching Power Supply will work, and produce AUX voltages Q2 is produced through ZD1 and R20
Constant conduction voltage, forces Q1 to remain off state.
Switching Power Supply starts connection circuit, and the circuit start of Switching Power Supply connects HV, and when Q1 is turned on, HV is low pressure, is compeled
It is closed Switching Power Supply；When Q1 is turned off, HV is high pressure, and Switching Power Supply is in running order.
