AC Power Regulator for Stabilizing Control – Fuji Electric APR APR is an abbreviation for AC Power Regulator. An APR is a device that can adjust AC voltage, current, and power steplessly. It is widely used for temperature control of electric furnaces and heaters, as well as for light dimming and AC stabilization power supplies. Fuji Electric’s APRs use thyristors, IGBTs, and other semiconductors as main devices to stabilize control. Application examples Voltage stabilization < Welding machines > < Electric discharge machines > Welding power supply Control device Machining equipment Heat controllers...

Fuji AC Power Regulator [APR] APR Model Selection Items There are three waveform control methods for APRs: a phase control method for switching with thyristors, a cycle control method, and a PWM control method for switching with IGBTs. Select a waveform control method after understanding the features of each method. Phase control method (APR-V, APR-D) The phase control method controls the voltage applied to the load from 0 to 100% by controlling the ignition phase angle α at each half cycle of the power supply frequency.

■ Features of each control methodThe phase control method, cycle control method, and PWM control method have the following features and are used in various ways. Item “Conversion factor Ki” of AC power regulator *The PWMAPR-M series supports B, C, and D as standard (switchable using the main unit setting). PWM-APR supports C only. D series single phase products support only T, A, and B, and three phase products support only T. Mini and aA series are not supported. For details, refer to “ ■ Feedback control method (PWMAPR-M, PWM-APR, APR-V)” on page 6 and the items in each series. —^Gradient setter^)-...

■ Fuji AC Power Regulator [APR] An APR without a feedback function outputs voltage in proportion to the output setting, but the output voltage and output current may vary due to power supply voltage fluctuations and load fluctuations. There are also loads such as those of pure metal heaters that draw several to ten times their rated current at low temperatures. Feedback control is a function that monitors the output status of the APR and automatically corrects the output so that the output is always as specified. The APR-V series offers the following feedback control methods to meet application...

APRs can be used for resistive loads (heater loads) and other loads, but the following precautions must be taken: Special attention should be paid to heater loads because the resistance value can vary greatly depending on the heater type and operating temperature, and the resistance values can change due to aging.
