The circuit consists of preamplifier, tone controls, and regulated DC power supply, while providing a power output of 18 Watts for 8 Ohm load and 30 Watts for 4 Ohms load. BC550 – an NPN general ...
The power factor corrector (PFC) front end of an off-line power supply is subject to the operating frequency limitation caused by the Miller Effect of its associated power MOSFET. This effect is a ...
