电力电子技术在电力系统中也起着举足轻重的作用，当电力系统离开电力电子技

Power electronics technology also plays an important role in the power system, power system when leaving the power electronics technology, the modernization of electricity will be difficult to achieve. Construction and development of the power system, has been supporting the power electronics technology, modern purpose can be achieved. Power transmission is based on the high-voltage transformer, and the voltage generated by the generator will then enhance its output after a new way. HVDC end and the end positions of an electrically, generally thyristor means to avoid long distance and large capacity transmission, no power electronics technology, the system will cause an outage occurs, the power transmission system uses technology based electronics provide good protection for the transmission. In power distribution systems, power electronics may also be used to control the power quality, such as flickering for an instantaneous power failure and power quality control of the voltage drop, the power supply to ensure better quality. Electronic power technology is widely used in transportation, dc, dc converter technology has been widely used in subway and trolley buses in the EMU. In use, it can be better controlled infinitely variable, improve quality control. In use, the most common presenting DC electric locomotive correction means selected locomotive as the power supply. However, if the frequency AC locomotives powered equipment, we do need power electronics and electric drives and power control help. For example: DC choppers are widely used in rail vehicles, power electronics technology widely used magnetic levitation train, which is a good technical requirements, key technology use cases. And electric vehicles, the battery will be used to provide energy, necessary to control the electric drive. After charging the battery using the power supply can not leave. Therefore, shipbuilding, avionics technology are inseparable.

Power electronic technology also plays an important role in power system, when the power system leaves power electronic technology, the modernization of power will be difficult to achieve. The construction and development of power system has been supporting the power electronics technology, the goal of modernization can be achieved. Power transmission is based on a high-voltage transformer, and the voltage generated by the generator will then increase its output in a new way. HVDC endpoint and end position by electricity, generally using the thyristor device, can avoid large-capacity and long-distance transmission, no power electronictechnology, the system will lead to power failure problems, transmission power electronic technology system using the technology base to provide good protection for transmission. In power distribution systems, power electronics can also be used to control power quality, such as for flashing and other transient power failures and voltage drop power quality control, to better ensure power quality. Electronic power technology is widely used in transportation, DC, DC conversion technology, has been widely used in subway and trolleybus in the locomotive group. In use, you can better control unlimited variable speed and improve quality control. In use, the most common rendering in DC electric locomotive correction refers to the selection of locomotives as power supplies. However, if the variable frequency AC locomotive power supply equipment, we really need the help of power electronics and electric drive and power control. For example: DC chopper is widely used in rail vehicles, power electronics technology is widely used magnetic levitation train, which is a good technical requirement, key technology use case. With electric vehicles, which will be used as batteries to provide energy, require sepsis control. Charge the battery after use and the power supply cannot be left. Therefore, ships, avionics technology is inseparable.
