1. A system comprising:
first converter circuitry connected across two terminals of a direct current (DC) bus;
second converter circuitry connected to:
one terminal of the two terminals of the DC bus via an electrical connection path, and
ground reference;
measuring circuitry configured to measure insulation between the first converter circuitry and the ground reference; and
control circuitry configured to:
control current from the second converter circuitry to the one terminal of the two terminals of the DC bus; and
adjust, based on measuring insulation by the measuring circuitry, an impedance of the electrical connection path.
