(it has to be connected to a transformer as it's part of a larger project). i have tested the transformer and the rectifier independently and they seem to work. however, when i put them together, they don't work as expected (images attached). the problem i'm facing seem...
A full bridge rectifier is a must have circuit in AC to DC converter circuits.It is made of 4 diodes. As I mentioned in the video, a diode is an electrical component that only allows the current in one direction to flow, and blocks it from going backwards....
Bridge circuits are among the most elemental and powerful electrical tools. They are found in measurement, switching, oscillator and transducer circuits. Additionally, bridge techniques are broadband, serving from DC to bandwidths well into the GHz range. The electrical analog of the mechanical beam ...
Although the 377 has a shield for the rectifier, choke and power transformer, it has nothing for the chassis underside. Mains and B+ transformer wiring radiates a lot of hum. I think to fix it, consider DC filament power and an extra shield for the HV AC stuff under chassis, as well ...
A synchronous full bridge rectifier is controlled to provide a power factor near unity. The full bridge rectifiers are transistors each with a controlling input. The AC input signal and currents within the circuit are sensed and sent to a controller. In response, the controller output control sig...
Can you confirm that the rectifier bridge isn't loaded by other components than Mohm resistors, e.g. capacitors? Yes, no other load is connected to the output of the diode bridge, and for this reason we are also surprised by the random burning of these diodes. Of course, it burns abo...

As far as I can tell, the only critical components that I need to worry about are the bridge rectifier and the 7812/7912. DC coming in is about +-15V, so the regulators need to dissipate about 1.4W each. I put a thermocouple on the 7812 (which is providing slightly more current than...
