Abstract
... 60Hz signal. By transistor C4016 and 12V/2V transformer, the signal is amplified in current domain and matched in impedance. Finally, the signal is amplified to 12V by transistor 2SC5200 and then converted to 110V AC by 12V/110V transformer. In 12V/220V circuit, the IC4047 generates an astable signa ...
