US Patent 10170911 Providing phase synchronization and harmonic harvesting

Techniques are described for reducing or dampening harmonics in a power signal to be supplied to a power system. The techniques may also be used to synchronize the power signal to be supplied to the power system with the power that is currently present on the power system. The techniques operate to step down the signals to be processed, process the signals using low-current op amps, and then step the signals back up to be transmitted on a high current system. The values of the circuit components may be determined by using a solution for an accompanying transfer function.
