Bridge Rectifier Controller circuit


The blog is the ideal place for storing useful technical info so I don't phone three people on a Saturday night for the diode polarity in a diode throttle and still assemble it backward (the silver band to the slow side, by the way ;-).

The circuit below is the popular Newcastle Full Throttle bridge rectifier version and, whilst simple, it is easily forgotten and a new project is shortly underway. In this case, it will feature six instead of five bridge rectifiers previously used for metal cars, with the two closest to full being switchable per the drawing, thus offering six sensitivity settings and usable from lead Scalex (6) right through to the hotter old fashioned specials (5).
A spare bridge rectifier was then used for the brake, similarly wired with the red brake cable going to switch "off" centre tap, neg (-) to the brake band plus one switch "on", and pos (+) to the other "on" switch position. Redundant by current use as way overkill and a better spread is obtained by potentiometer or rotary switch with 1amp diodes.
