Original Abstract Submitted
A DC-DC converter circuit includes a high-side transistor, a low side transistor, a gate driver power supply, a converter control, and a capacitance divider network. The high-side transistor includes a high-side drain terminal, a high-side source terminal, and a high-side gate terminal. The high-side drain terminal is coupled to a positive DC supply terminal. The gate driver power supply is electrically isolated from the high-side transistor and the low-side transistor. The converter control is configured to supply high-side control commands and low-side control commands to the high-side transistor and the low-side transistor, respectively. The capacitance divider network includes a first capacitor and a second capacitor. The first capacitor is electrically connected in series, at a DC-link midpoint node, to the second capacitor. The DC-link midpoint node, the gate driver power supply, and the converter control are all electrically connected to, and share, a local electrical ground.
