Abstract
Systems and techniques are provided for a power receiver circuit. A power receiver circuit may include power generating elements that may generate alternating current. The power receiver circuit may include group circuits that may connect power generating elements in parallel to combine the alternating current from the power generating elements into a single alternating current. The power receiver circuit may include rectifier circuits which may include rectifier channels connected to the group circuits and may include a rectifier that may generate direct current from alternating current. The power receiver circuit may include a step down converter connected to rectifier circuits that may convert direct current to direct current of a target voltage level. An output switch and linear regulator may be connected to the step down converter, and a microcontroller may be connected to the linear regulator and the output switch and may control the output switch.
