Learn more WhatsAppYou only answered half my questions. 27Vac means that the capacitor will charge to a peak value of 1.414*27 - 2*Vf (forward drop of the rectifiers). Vf is about 1V for most large silicon rectifiers. So unloaded voltage will be ~ 38 - 2 = 36V. Under load, the capacitor will charge to a value less than the 36V, mostly due to the impedance of the …
Learn more WhatsAppA step-up transformer converts the voltage on the primary side into a higher voltage on the secondary side. A step-up transformer does this by the ratio across its primary and secondary windings. The turns in a winding featured on a step-up transformer will always be higher on the secondary side than the primary side.
Learn more WhatsAppThe transformer above (Avel Y236907 800VA 45V+45V Toroidal Transformer), for example, will try to draw over 100 Amps on the first cycle of 60 Hz Power. To keep a large transformer from being damaged at turn-on (and to keep it from saying "ow"), or to keep a breaker from popping, you put in an inrush current limiter circuit.
