Abstract
An alternating current (AC) impedance spectroscopy method includes providing an AC impedance spectroscopy ripple from power electronics into an electrochemical device, and absorbing the ripple in the power electronics.
Claims22
An alternating current (AC) impedance spectroscopy method, comprising:
- providing an AC impedance spectroscopy ripple from power electronics into an electrochemical device, wherein a power factor corrected (PFC) rectifier is in electrical communication with an AC power source via an AC split bus and to a direct current/direct current (DC/DC) converter via a DC bus, and
- absorbing the ripple in the power electronics, wherein an auxiliary electric power converter draws a reactive power amount from a DC-link to cancel a ripple current drawn by the DC/DC converter.
A circuit for alternating current (AC) impedance spectroscopy, the circuit comprising:
- a power factor corrected (PFC) rectifier in electrical communication with an AC power source via an AC split bus and a direct current/direct current (DC/DC) converter via a DC bus, the PFC rectifier providing an AC impedance spectroscopy ripple into an electrochemical device;
- and
- an auxiliary electric power converter drawing a reactive power amount from a DC-link to cancel a ripple current drawn by the DC/DC converter.
