High-side gate drivers to be used in EVs and HEVs should target high insulation voltage, as well as efficiency and monitoring capability.

Abstract
High-side gate drivers to be used in EVs and HEVs should target high insulation voltage, as well as efficiency and monitoring capability. In traditional step-down converters, the entire control stage is referred to ground, thus either a pulse transformer or an isolated integrated gate driver is required. The paper proposes a buck converter having the entire control unit referred to the floating node. The design was carried out considering discrete components, which allows for low-cost and low-profile implementation. Simulations were conducted to validate the proposed converter, and to compare it with traditional high-side gate driver topologies. The overall efficiency results to be consistent with the other topologies, whereas the estimated occupied area and the cost, at PCB level, are both significantly lower.Pubblicazioni consigliate
