Abstract:
GaN-based half bridge power conversion circuits employ control, support and logic functions that are monolithically integrated on the same devices as the power transistors. In some embodiments a low side GaN device communicates through one or more level shift circuits with a high side GaN device. Both the high side and the low side devices may have one or more integrated control, support and logic functions. Some devices employ electro-static discharge circuits and features formed within the GaN-based devices to improve the reliability and performance of the half bridge power conversion circuits.

Claim (Index 17):
A method of using a charging circuit, the method comprising:\n allowing current to flow from a ground referenced power supply node to a first floating power supply terminal with a semiconductor circuit, wherein the semiconductor circuit comprises: a first enhancement-mode transistor, comprising:\n a gate configured to be controlled by a gate drive circuit control signal, \n a source directly connected to the ground referenced power supply node, and \n a drain directly connected to the first floating power supply terminal, \n wherein the first enhancement-mode transistor is configured to allow current to flow from the ground referenced power supply to the first floating power supply terminal in response to the gate drive circuit control signal; and \n a second enhancement-mode transistor, comprising:\n a gate connected to the ground referenced power supply node, \n a source directly connected to the ground referenced power supply node, and \n a drain directly connected to the first floating power supply terminal.
