Patent
Navitas | Date: 2015-09-17

A semiconductor device is disclosed. The device includes a substrate including GaN, a two dimensional electron gas (2DEG) inducing layer on the substrate, and a lateral transistor on the 2DEG inducing layer. The lateral transistor includes source and drain contacts to the 2DEG inducing layer, a gate stack between the source and drain contacts, and a field plate between the gate and the drain contact. The device also includes one or more insulation layers on the 2DEG inducing layer, where the field plate is spaced apart from the 2DEG inducing layer by the insulation layers, and a conductor on the insulation layers, where a first portion of the conductor is spaced apart from the 2DEG inducing layer by the insulation layers by a distance less than 200 nm.


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. Various embodiments of level shift circuits and their inventive aspects are disclosed.


Patent
Navitas | Date: 2015-12-14

Electronic packages are formed from a generally planar leadframe having a plurality of leads coupled to a GaN-based semiconductor device, and are encased in an encapsulant. The plurality of leads are interdigitated and are at different voltage potentials.


Patent
Navitas | Date: 2016-02-22

Leadless electronic packages for GaN-based half bridge power conversion circuits have low inductance internal and external connections, high thermal conductivity and a large separation between external connections for use in high voltage power conversion circuits. Some electronic packages employ L shaped power paths and internal low impedance die to die connections. Further embodiments employ an insulative substrate disposed within the electronic package for efficient power path routing and increased packaging density.


Patent
Navitas | Date: 2015-08-14

A gallium-nitride based power transistor is coupled to a voltage source that has transient overvoltage conditions exceeding the allowable withstanding voltage of the power transistor. An overvoltage protection circuit is coupled to the power transistor to temporarily turn on the power transistor during the overvoltage condition to protect the power transistor from overvoltage breakdown.


A control scheme and architecture for a power conversion circuit employs two bidirectional switches and a zero voltage switching (ZVS) scheme for the high-side switch. Methods of incorporating the control scheme into multiple power conversion circuit topologies are disclosed. Methods of device integration including co-packaging and monolithic fabrication are also disclosed.


Patent
Navitas | Date: 2016-01-26

A control scheme and architecture for a wireless electrical energy transmission circuit employs two solid-state switches and a zero voltage switching (ZVS) topology to power an antenna network. The switches drive the antenna network at its resonant frequency and simultaneously energize a separate resonant circuit that has a resonant frequency lower than the antenna circuit. The resonant circuit creates out of phase voltage and current waveforms that enable the switches to operate with (ZVS).


Patent
Navitas | Date: 2015-06-18

An electronic circuit is disclosed and described herein. The circuit includes first and second pins, and an overvoltage protection circuit including a first enhancement-mode transistor. The overvoltage protection circuit is disposed on a GaN-based substrate, and the first enhancement mode transistor is configured to provide overvoltage protection between the first and second pins.
