The regulators/rectifiers are charging control devices that rectify the power output from the ACG, charge batteries, and maintain fixed battery voltages, but do not supply batteries with extra ACG output. A broad range products are available, ranging from miniature AC/DC regulators/rectifiers to large three-phase regulators/rectifiers.

- Structurally designed to withstand high temperature conditions, providing high reliability
Single-Phase Regulator/Rectifier for Small Motorcycles
AC/DC LED H/L Control Regulator/Rectifier
These regulators/rectifiers charge the battery during the positive cycle of the ACG output, and light up the head light (LED H/L) during the negative cycle. An electrolytic capacitor is built-in as the power supply for lighting the LED H/L and a stable LED light can be controlled even with an AC half wave.
AC/DC Valve Control Regulator/Rectifier
These regulators/rectifiers charge the battery during the positive cycle of the ACG output, and light up the valve headlight during the negative cycle. By optimizing the valve headlight control, the ACG output efficiency can be improved. There is an electrolytic capacitor built into the power terminal for the FI (fuel injection) system, enabling the system to function even without a battery.
Single-Phase Open Regulator/Rectifier
The ACG output is rectified to charge batteries. When the battery voltage is high, these regulators open the ACG output and control the charging. Opening the ACG output reduces ACG loss. An electrolytic capacitor is built into the regulator/rectifier output, enabling the system to function even without a battery.
Single-Phase Short Regulator/Rectifier
The ACG output is rectified to charge batteries. When the battery voltage is high, these regulators/rectifiers short the ACG output and control the charging.
Three-Phase Regulator/Rectifier for Mid-Size & Large Motorcycles
Three-Phase Open Regulator/Rectifier
The ACG output is rectified to charge batteries. When the battery voltage is high, these regulators/rectifiers open the ACG output and control the charging. Opening the ACG output reduces ACG loss.
Three-Phase Short Regulator/Rectifier
The ACG output is rectified to charge batteries. When the battery voltage is high, these regulators/rectifiers short the ACG output and control the charging.
Three-Phase Short Regulator/Rectifier (FET)
These regulators/rectifiers use MOSFETs and Schottky barrier diodes for the ACG output control elements to produce a synchronous rectification and achieve low-loss and large current. These three-phase short regulators/rectifiers can control up to high generator frequencies.
Phase Control Regulator/Rectifier
The CPU uses the sensor signals to control the electric conduction phase for the ACG output, and then this regulator/rectifier increases or decreases the generator current to control the charging. Controlling the electric conduction phase improves the generator performance. The MOSFET is used for all control elements, and this three-phase short regulator/rectifier (FET) helps achieve low-loss and large current.
