Application of TDK high-power field effect tube full-bridge components in switching power supplies and class D amplifiers 01

The ultra-high-power field-effect full-bridge component with model number EA40A906 is a product of Japan's TDK and has been certified by UI No. 1 in the United States. After dissection, the principle is shown in Figure 7-17. 6 Four ultra -power
field effect tubes with thick gold-sealed legs are installed on a precision milled chrome-plated copper block, insulated and then placed on a mirror-plated plate with a thickness of 8mm. On the copper block, all the heat dissipation blocks add up to about t kilograms. Other components are installed on two double-sided metal perforated epoxy boards. The input end is a refined special socket, and the output is a refined Bakelite terminal block.
