Modular power electronic device platform

Abstract

The invention discloses a modularized power electronic device platform which comprises a power module, a multi-channel sampling and conditioning module, a signal adapter plate and a controller module. The power module is connected with the multi-channel sampling and conditioning module to obtain a target sampling signal and feeds the target sampling signal back to the controller module; a control signal sent by the controller module is sent to the power module through the signal adapter plate; the weak current interface of the power module is connected with the signal adapter plate, and the controller module interacts with the power module through the signal adapter plate. The modularization, the reusability, the reliability, the usability and the flexibility of the power electronic device platform can be enhanced.

Description

technical field [0001] The invention belongs to the technical field of power electronic devices, and relates to a modular power electronic device platform. Background technique [0002] The current power electronic device platform is often aimed at a single fixed topology, such as the common three-phase inverter experimental platform, which is a fixed topology composed of three-phase six switching tubes, which can only be used in three-phase inverter applications; power electronics for novel topologies The device platform is a novel topology structure directly composed of switching devices, which cannot be used in other topologies. The construction of this kind of experimental device often needs to design the power part, weak current control part, power device drive, sampling and control part from the beginning to the end according to the topology type. The device used for a fixed topology cannot be used for other topologies, which greatly increases device cost. In additio...

AI Technical Summary

Problems solved by technology

When the protection logic (overvoltage protection, overcurrent protection, overheat protection, etc.) is not considered in place, the independently designed platform often burns out due to uncertain factors during the experiment, which affects the experiment process and cost control

In addition, the separately designed platform sampling and conditioning circuits are often only suitable for the working conditions and range of the platform itself, and are fixedly welded on the separately designed platform, which cannot be reused on other power electronic platforms

Because the sensors used for sampling and conditioning are expensive, it causes a large waste of resources

[0003] To sum up, the current common power electronic device platforms are often aimed at a single topology and cannot be reused to other topologies; the design threshold required for stable and reliable operation of the device is high, and it is impossible to guarantee a successful platform design; the workload of device design is relatively large , unable to quickly conduct experiments and verify ideas

Ultimately lead to higher time cost and material cost
