HIGH VOLTAGE CAPACITORS

High frequency inverter front stage output

The high-voltage output generated by the front-stage transformer passes through the high-frequency transformer to output high-frequency alternating current, and then a high-frequency hundreds of V direct current is output to the back-stage mosfet/IGBT through the fast recovery diode full bridge rectification, and then the back-stage IC generates 50Hz control signal which is used to control the work of the mosfet/IGBT of the subsequent stage, and then output 120v/ 220v/ 230v/ 240v V 50/60Hz alternating current.

Communication emergency high altitude base station

In the last few years, a new set of options have been added in the form of high al-titude platform stations (HAPS) and unmanned aerial vehi-cles (UAVs) that operate as mobile telecom providers, mos-tly operating at stratospheric altitudes of ~20 km, or other low altitudes, above earth; in our days, it has been deeply studied that near-space platforms could be safely deployed at altitudes in the 17-25 km range.
