The invention discloses a primary side and secondary side control quantity constraint method and device and a wireless charging system. The primary side and secondary side control quantity constraint method comprises the steps of: acquiring a primary side self-inductance value of a loose coupling transformer and a primary side compensation inductance value, the output power and the secondary side efficiency of the wireless charging system are obtained; determining a constraint target of the wireless charging system; and calculating the primary side and secondary side control quantity constraint condition of the wireless charging system according to a preset formula so as to control the operation of the wireless charging system. According to the technical scheme, the reliability of the wireless charging system is improved.
