FISM096A1 is a modular sine-wave inverter controller that is used to convert dc power to ac power of adjustable frequency and volts. This technology is widely used for portable power supplies, industrial or commercial application.

The FISM096A1 is designed as a current-mode PWM multi-loop digital closed-loop sine-wave inverter, which allows for sine-wave output voltage stability and low electromagnetic interference. Its parameterization function allows for easy adjustment of the output to meet the needs of various motor drive applications.

In addition, the FISM096A1 can be used as battery optimization and over-voltage protection by controlling the voltage of the battery, thus preventing the dramatically reduce the cost of the system. Its embedded fault current detection circuit and fault message logic process ensure reliable, long-term operation.

The working principle of the FISM096A1 can be summarized as follows. When an input voltage greater than a certain threshold value is applied, the FISM096A1 will firstly police the output voltage until it becomes stable. This process is known as the closed-loop regulation process. To achieve this, the FISM096A1 uses two separate loops.

The inner loop consists of two sets of voltage regulation loops and current regulation loops, and is used to adjust the output voltage. In the voltage regulation loops, a voltage error amplifier and a voltage regulator feedback circuit are used. The voltage error amplifier uses the difference between the actual output voltage and the setpoint voltage as its input signal and then adjust the output frequency. The current regulation loops also include a current error amplifier and current regulator feedback circuit. It works to stabilize the voltage waveform and reduce the ripple effect.

The outer loop is used to adjust the output current. For this purpose, a current sensor is used to compare the actual output current and the reference current, and adjust the output power accordingly. This loop ensures the reliability and stability of the output current.

Furthermore, FISM096A1 has two operating modes: normal and fault. In normal mode, all the loop are running normally and the output voltage and current can reach the setpoint. In fault mode, all the loop are shut down immediately and the output voltage and current are all set to zero. This mode ensures safety and reliability.

The wide application field of FISM096A1 includes renewable energy, power supplies, motor drives, telecommunications, and uninterruptible power supply technology. Moreover, this technology has the thermal stability to operate in extremely high temperature environments, for example, automotive electronic control system.

FISM096A1 is a reliable, modular, and high-performance inverter controller that is well suited for a variety of applications. It is equipped with multiple regulation loops to ensure a stable output voltage and current, and has the capability of monitoring output current to ensure safety. This technology is widely used in the industries which need power conversion from dc to ac power.
