Feature and Benefits

The S-1701R3315-U5T1G, with its high precision and fast response, is an ideal choice for applications requiring high accuracy, speed and stability. It offers a wide range of control and protection options, including over-current, over-voltage and under-voltage protection, temperature and current limiting, as well as PWM or pulse-width modulation stage control.The S-1701R3315-U5T1G also offers users the ability to program voltage setpoints for each phase individually, making it ideal for multi-phase power systems. The device also features an automatic frequency detection capability and low power consumption, both of which make it ideal for low power applications.

Working Principle

The S-1701R3315-U5T1G is based on a three-phase voltage control system. It employs a proportional integral (PI) controller, which uses a two-loop control system to maintain accurate voltage regulation. The input voltage is first sampled by an analog-to-digital converter (ADC) and the resulting signal is then filtered and amplified. The resulting signal is then compared with a reference signal, which is programmed by the user. The output of the PI controller is then used to generate appropriate control signals to the PWM stage and the current limitation control stages. The PWM stage converts the analog signal into a digital signal and the current limitation control stage limits the flow of current in the output stage. The result is a stable and accurate regulated voltage.

Conclusion

The S-1701R3315-U5T1G from Toshiba is a three-phase controllable voltage regulator that can provide high accuracy and fast response to dynamic changes in input voltage. It is suitable for a wide range of power conversion, electro-mechanical systems and industrial instrumentation applications, with features such as automatic frequency detection, low power consumption and user programmable voltage setpoints for each phase. The device is based on a proportional integral (PI) controller which uses a two-loop control system to maintain accurate voltage regulation.
