IC697CMM742-LL Modern Electronic Systems

IC697CMM742-LL first add Vge and to be stable (cut-off bias -15V, conduction bias +15V), and then can add Vce. Do not when the G-pole overhang or not stable on the addition of Vce (a few hundred a thousand volts), because of the coupling capacitance of the Cgc poles between the IGBT can be mistakenly conduction, so that too high dv/dt caused by electrical breakdown and damage. In order to avoid the occurrence of the above phenomenon generally use the delay circuit method, so that Vce delay Vge about 0.2 seconds, which greatly improves the use of security, reliability, especially in high-power devices should be noted.

IC697CMM742-LL Simulation of modern electronic systems using power appliances has always been a challenge due to the nonlinear properties of power switches, the connection to continuous subsystems and the design of discrete-time controls. Nowadays, simulation studies are also used in more and more complex systems in order to design effective control countermeasures. Examples are renewable energy conversion systems, complete traction systems, etc. In these cases, the actual control of an effective simulation is required.

The part of IC697CMM742-LL has been dedicated to power based on specific circuit libraries such as PSCAD (professional tool for power system simulation), CASPOC (power electronics and electrical drive modelling and simulation software), PSPICE (design and simulation of analogue and digital circuits), PSIM (simulation software design for power electronics, motor control, and dynamic system simulation), and other power Simulation of electronic performance. Other software can efficiently control the development, based on specific system libraries or toolboxes, e.g.:MATLAB/Simulink.The use of such software is valuable for the direct generation of real-time control algorithms, such as obtaining dSPACE controller boards.
