我们可提供演示并联 MOSFET 的演示板: 低压驱动可扩展电源演示板相关产品系列及设计支持 在开关条件下实现并联会更加困难,随着频率的增加,更是如此。并联 MOSFET 时,必须了解、确保 MOSFET 之间合理的电流平衡,还要了解影响均流、导通损耗、开关损耗的 MOSFET 参数,以及栅极阈值电压对器件温度的重要性。 英飞凌一流的 ...
This article proposes a generic zero-voltage switching (ZVS) scheme for parallel power MOSFETs. Uncoupled or inversely coupled differential-mode commutation inductors are added to the midpoints (ac terminals) of parallel MOSFET half-bridges, and a time-delay-based control scheme is applied, generati...
The answers to these questions depend on the specific operating state of each of the devices. This paper discusses both gain and temperature coefficient considerations for new generation Power MOSFETs. Suggestions are made which allow for simple and economical device matching in the field.John W. ...
One scheme that has been used before when multiple MOSFETs are preferred for spreading out the power dissipation is to use FETs with a lower miller plateau and supply the UCC24624 with a lower VDD voltage (~5V or so). The gate charge will be smaller while still b...

MOSFETs is limited to about 200 A; thus, for higher-current applications, discrete die could be paralleled together. Paralleling of power modules at higher current levels is a more practical approach, as each module is optimized for the effect of parasitic inductances and capacitances and can ...
Paralleling power MOSFETsThere is a continuous need for higher power capability in most applications today. In some applications, a single MOSFET is not enough. In these applications, designers must share the current load among multiple MOSFETs in parallel. Connecting MOSFETs in parallel while ...
Increasing the capability of a power switch by using several individual MOSFETs connected in parallel is a common practice with silicon semiconductor devices. This paper deals with the results of an investigation of the issues linked to paralleling the Silicon Carbide (SiC) MOSFETs. Based on ...
