6 FAQs about 12v wind power rectifier system

Do wind turbines need a rectifier?

In a small wind power system that operates independently, the alternator driven by the wind turbine needs to be equipped with an appropriate rectifier to charge the battery. Rectifier can generally be divided into two categories: mechanical rectifier and electronic rectifier.

How many watts can a 12V wind turbine handle?

As an example, for a system voltage of 12V the maximum current is 1000W / 12V = 83A. This leads to a power loss within each diode pair of 67W, giving a maximum total heat dissipation in the rectifier of around 200W. To dissipate this heat, a heatsink is required and the unit is mounted at the top of the wind turbine tower.

How does a rectifier work?

More technically, the rectifier allows current only to flow one way, hence the output waveform shown labelled 'with no battery connected'. When the battery is connected, power is transferred from the alternator to the battery only when the output voltage of the coil is higher than the system (which is the same as the battery bank) voltage.

What are the different types of rectifier circuits?

Common rectifier circuits include single-phase half-wave rectifier circuits, single-phase full-wave (double half-wave) rectifier circuits, single-phase bridge rectifier circuits, and three-phase half-wave rectifier circuits (zero-type rectifier circuits). circuit) and three-phase bridge rectifier circuit.

What are the circuit diagrams of a rectifier circuit?

The circuit diagrams of various rectifier circuits, the output voltage (rectified voltage) waveform, the output DC voltage, the output DC current, the maximum reverse voltage withstand by the diode and the average current flowing through each diode are shown in the table.

Why is a rectifier less expensive with a higher voltage?

It is assumed here that the system voltage has already been decided upon (see 'Wind Turbine Electrical System Design Guide' for more details). As mentioned in that guide, the rectifier will be less expensive with a higher system voltage, due to the higher currents at lower voltages.
