In this paper, a novel 4H-SiC LDMOS structure with a trench heterojunction in the source (referred as to THD-LDMOS) is proposed and investigated for the first time, to enhance the reverse recovery performance of its parasitic diode. Compared with 4H-...
In this paper, a 650 V 4H-SiC trench Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) with a hetero-junction diode (HJD) and double current spreading layers (CSLs) is proposed and studied based on Sentaurus TCAD simulation. The HJD suppress...
This study proposed a novel 4H-SiC double trench metal-oxide-semiconductor field-effect-transistor (DTMCD-MOSFET) structure with a built-in MOS channel diode. Further, its characteristics were analyzed using TCAD simulation. The DTMCD-MOSFET comprise...
In this study, a novel silicon carbide (SiC) double-trench MOSFET (DT-MOS) combined Schottky barrier diode (SBD) and MOS-channel diode (MCD) is proposed and investigated using TCAD simulations. The integrated MCD helps inactivate the parasitic body d...
In this study, a novel MOS-channel diode embedded in a SiC superjunction MOSFET (MCD SJ-MOSFET) is proposed and analyzed by means of numerical TCAD simulations. Owing to the electric field shielding effect of the P+ body and the P-pillar, the channel...
In this article, a novel double-trench SiC MOSFET with an integrated MOS-channel diode (MCD) is proposed and analyzed through TCAD simulations. The MCD incorporates a short channel, where the channel length can be adjusted by modifying the recess dep...
A novel Silicon-Carbide heterojunction U-MOSFET embedded a P-type pillar buried in the drift layer (BP-TMOS) is proposed and simulated in this study. When functioning in the on state, the merged heterojunction structure will control the parasitic bod...
A totem-pole bridgeless boost converter is one of the most promising topologies for the power factor correction (PFC) stage in high-power applications due to its high efficiency and small number of components. However, due to the totem-pole structure...
