Normally, both are charged from a single alternator, and a heavy-duty split-charge diode is used to prevent the higher-charge battery (typically the engine battery) from discharging through the lower-charge battery when the alternator is not running. Diodes are also used in electronic musical keyboards.

The main alternator is the larger of the two sections, and the smaller one is the exciter. The exciter has stationary field coils and a rotating armature (power coils). The main alternator uses the opposite configuration with a rotating field and stationary armature. A bridge rectifier, called the rotating rectifier assembly, is mounted on the ...
Thyristors are commonly used in place of diodes to create a circuit that can regulate the output voltage. Many devices that provide direct current actually 'generate' three-phase AC. For example, an automobile alternator contains nine diodes, six of which function as a full-wave rectifier for battery charging.
If connected in series with the circuit it simply prevents reversed current, but if connected in parallel it can shunt the reversed supply, causing a fuse or other current limiting circuit to open. All semiconductor diodes have a threshold voltage – typically between 0.5 volt and 1 volt – that must be exceeded before significant current ...
The DIAC (diode for alternating current) is a diode that conducts electrical current only after its breakover voltage, V BO, has been reached momentarily. Three, four, and five layer structures may be used. [1] Behavior is similar to the voltage breakdown of a triac without a gate terminal.
A circuit that behaves like a snap-action switch, suddenly changing state as an analog signal increases; displays hysteresis. Schottky diode A diode that relies on the junction between a semiconductor and a metal. Scott-T transformer A transformer connection for balanced interconnection of a two-phase system and a three-phase system. s-domain
Diode circuit implementing AND in active-high logic. Note: in analog implementation exact output currents will be different from +5V supply. This circuit mirrors the previous gate: the diodes are reversed so that each input connects to the cathode of a diode and all anodes are connected together to the output, which has a pull-up resistor.
