Impact of junction temperature over forward voltage drop for red, blue and green high power light emitting diode chips

2017 16th IEEE Intersociety Conference on Thermal and Thermomechanical Phenomena in Electronic Systems (ITherm), 2017
Commercially available light emitting diodes (LEDs) that have high efficiencies and long lifetime are offered in advanced packaging technologies. Many cooling systems were developed for current LED systems that enable a better removal of heat than counterpart devices offered earlier this decade.

An AlGaAs/GaAs hetero source bipolar mode static induction transistor (HBSIT) with low forward voltage drop and high current gain

Proceedings of the 6th International Symposium on Power Semiconductor Devices and Ics, 2002
A new 550 V AlGaAs/GaAs Hetero source Bipolar mode Static Induction Transistor (HBSIT) has recently been developed and fabricated. The GaAs HBSIT is considered to be superior to conventional Silicon power devices in on-state characteristics. For an example, forward voltage drop of 0.3 V can be obtained at current gain of 150 and drain current density ...

Simulation of High-Voltage Injection-Enhanced 4H-SiC N-Channel IGBTs with Forward Drop Approaching that of a PiN Junction Rectifier

Materials Science Forum, 2006
For SiC devices capable of blocking very high voltages (>4kV), it becomes imperative to use bipolar devices because of unacceptably large on-state losses of unipolar devices. The IGBT offers the potential for high current density operation and ease of turn off using a MOS gate structure.

A direct torque controlled interior permanent magnet synchronous machine drive with compensation of the forward voltage drops of the power switches

38th IAS Annual Meeting on Conference Record of the Industry Applications Conference, 2003., 2004
The direct torque control (DTC) scheme is a new control scheme based on space vector theory. However, at low speed, the performance is not very good. The effect of forward voltage drop on DTC performance at low speed is analyzed and compensated in this paper. Modeling results show that the blindness to the forward voltage drop of the power switches may

Improved low speed performance of a PI-DTC interior PM machine with compensations of dead-time effects and forward voltage drops

2007 7th Internatonal Conference on Power Electronics, 2007
The performance of direct torque control (DTC) interior permanent magnet (IPM) machines at low speed is poor due to a few reasons, namely limited accuracy of stator voltage acquisition and the presence of offset and drift components in the acquired signals.

Utilizing low forward voltage drop power semiconductors to minimize heat sinking requirements in multichip module DC solid state relays and static switching applications

Proceedings. 1998 International Conference on Multichip Modules and High Density Packaging (Cat. No.98EX154), 2002
This paper provides a concise overview of the impact of new ultra low RDS(on) MOSFET technology, low V/sub f/ Schottky technology, and low V/sub ce(on)/ bipolar technology devices as applied to control of low voltage DC power. Device selection criteria and circuit topologies are provided along with empirical and FEA modeling data on heat sinking and ...
