Wireless power system

A wireless power system comprising:

• a wireless power transmitter operatively connected to an input power source, the wireless power transmitter configured to deliver power from the input power source wirelessly to one or more wireless power receivers that are placed within a charging zone of the wireless power transmitter,
• wherein when a wireless power receiver is placed within the wireless power transmitter's charging zone, the wireless power receiver is configured to receive power wirelessly to deliver the received power to its load;
• wherein while receiving power wirelessly if the wireless power receiver detects a surge of received power exceeding safety thresholds, the wireless power receiver performs one or more of:
• adjusting its impedance network to reduce the amount of power delivered to rectifier of the wireless power receiver,
• adjusting the rectifier configuration to reduce the amount of power delivered to the load,
• increasing the amount of filtering capacitance at the output of the rectifier,
• to ensure that its internal circuitry is protected from damage without specific assistance from the wireless power transmitter.
