Abstract
A modular power converter is operable to mitigate a DC component of injection onto a power transmission line. The modular power converter includes a pulse width modulation (PWM)-controlled generator, a voltage emulator, and a control circuit. The PWM-controlled generator includes drivers and a coupling capacitor. The PWM-controlled generator is to store voltage on the coupling capacitor and inject a voltage of the converter, which includes the DC component of injection, onto the power transmission line. The voltage emulator is to determine a DC measurement emulating the voltage of the converter, as a time-varying average value that is based on summing generator driver-state weighted values of the voltage on the coupling capacitor. The control circuit is to generate PWM pulses to operate the PWM-controlled generator and adjust timing of the PWM pulses, based at least on the DC measurement from the voltage emulator to counter-balance the DC component of injection.
