Abstract

The invention relates to the technical field of IPM protection circuits, in particular to an IPM protection system for flywheel energy storage devices. The IPM protection system comprises a signal generation unit, an IPM unit, a short-circuit protection unit, an over-temperature protection unit, an over-current protection unit, a comparator and a line driver. The signal generation unit generates and outputs a first pulse signal and a second pulse signal. The line driver is connected with the comparator, the IPM unit and the signal generation unit. The comparator outputs a turn-off signal according to output signals of the short-circuit protection unit, the over-temperature protection unit and the over-current protection unit. The line driver controls whether the first pulse signal and thesecond pulse signal are transmitted to the IPM unit or not according to the turn-off signal. The IPM protection system is all composed of hardware. Compared with a software and hardware combined system, the system structure is simplified, the system development difficulty is reduced, the safety and accuracy of the system are improved, and the information processing efficiency is also remarkably improved.

Description

technical field [0001] The invention relates to the technical field of IPM protection circuits, in particular to an IPM protection system for a flywheel energy storage device. Background technique [0002] IPM (Intelligent Power Module) is an advanced new power switching device, which has the advantages of GTR (high power transistor) high current density, low saturation voltage and high voltage resistance, and MOSFET (field effect transistor) high input impedance, high switching Advantages of frequency and low drive power. IPM integrates logic, control, detection and protection circuits, which is easy to use and has a wide range of applications. It not only reduces the size of the system and development time, but also greatly enhances the reliability of the system, adapting to the development direction of today's power devices, such as modules Integrated, compound and power integrated circuits (PICs) have received more and more attention in the field of power electronics. ...
