The NK5EPC50Y is an intelligent three-phase integrated power module from Toshiba that is used in photovoltaic applications. It contains an MCU based on the NXP 567MHz STM32F767 MCU along with dedicated external peripherals, like temperature sensors, power management unit, and an embedded LIN bus interface for communication. The MCU is also embedded with high-speed I/Os for PC-level control of the PV system. The module includes a powerful oscillator and interconnects, which are critical for handling the high-speed operation of photovoltaic applications.

The NK5EPC50Y is designed for use in medium-to-large scale PV systems, where it is used to regulate voltage and current by modulating the power output at the AC-side terminals. The module’s MCU is programmed to control the converter and act as a gateway to fieldbus protocols like Modbus and DNP3. It is also capable of monitoring and control of AC and DC branch current, permitting the protection of connected electronics and photovoltaic systems.

The module requires a complex electrical network to efficiently and safely control these systems. The MCU is used to analyze the output of a large number of sensor and current data points, which require advanced digital algorithms that must be highly optimized in order to control the correct power rating. By using intelligent peripheral hardware and embedded software, the NK5EPC50Y module is able to provide a more efficient and reliable control system.

On the AC-side, the NK5EPC50Y controls AC voltage and current using pulse width modulation. By controlling both the voltage and current along with the power factor, the module achieves optimal power efficiency. On the DC-side, the module manages the DC voltage and current output to optimize the power output. It also has a built-in shunt, which can be used to measure the current passing through the PV system.

In addition, the MCU of the NK5EPC50Y has an integrated LIN bus receiver, which provides basic communication capabilities. This can be used in conjunction with other devices in the PV system to establish an effective communication network. With this communication network, the module can provide remote monitoring and control, as well as alarms or fault detection in the system.
