要約

The design of E class self-excited oscillating generator, which makes it possible to extend frequency bandwidth, where high efficiency and constant output power are preserved, is considered. The oscillator on MOS transistor IRF510 with operating frequency 3 MHz and output power 1 W is designed and experimentally tested. The obtained efficiency is 89 % at the output power is 0.7 Wand the dc voltage is 6 V. The proposed structure can be used in the FSK systems
