An optimizer (10), a photovoltaic power generation system and a photovoltaic power generation control method. The optimizer comprises a positive electrode branch (101), a negative electrode branch (102), a first voltage sensor (131), a first capacitor (151), a second voltage sensor (132), a second capacitor (152), an optimizer switch (12), an optimizer controller (11) and a third current sensor (143) or a first current sensor (141) and a second current sensor (142). The photovoltaic power generation system comprises a photovoltaic string unit (01), a photovoltaic inverter (02), a wake-up power source (03) and a wake-up switch (04); The photovoltaic string unit includes at least one group of photovoltaic panels and said optimizer. The optimizer overcomes the disadvantages that a weak electrical signal has a short communication transmission distance, easily affected communication robustness and high communication costs, and thus a dedicated weak electrical signal communication module can ...
