Digitization.
In conventional power electronics, control part is based on analog signals to design and work. In the sixties and seventies, power electronics technology is built entirely on the basis of analog circuits.
But now the digital signal and digital circuits become more and more important, digital signal processing technology has a sound and mature, showing a growing number of advantages: easy control of computer processing to prevent distortion of the analog signal distortion, reduce the spurious signals interference (to improve immunity), easy to debug and remote telemetry package remote adjustment, but also facilitate self-diagnosis, fault-tolerant techniques for implantation.
Therefore, in the eight, the nineties, for the various types of circuits and systems design, the simulation is useful, in particular: such as the printed version of the layout, electromagnetic compatibility (EMC) issues and the power factor correction (PFC), etc. solve the problem, can not do without the knowledge of analog technology, but for intelligent switching power supply, need to use the computer control, digital technology can not do without the.
