Wireless Transmission of IGBT Driver Control

In a commutation cell, the implementation of IGBT and MOS requires an insulated signal. Traditionally, the insulated signal is carried out by a DC supply with a high insulation transformer for energy transmission and an optical fiber or pulse transformer for the switch control information. A new approach seems promising: the switch control information by a wireless transmission. Analog or digital switch control informations are envisaged. Experimental tests were done on a 1 kW buck converter controlled with a 2.4 GHz video transmitter.
