Energy storage NPC usually refers to the NPC (Neutral Point Clamp) three-level inverter used in energy storage systems. NPC three-level inverter is a multi-level inverter topology widely used in energy storage systems or photovoltaic systems due to its advantages such as low switching losses, small output current ripple, optimized power density, and efficiency.

Crystal oscillators mainly play the following roles in energy storage NPC (Neutral Point Clamp) systems:

Signals for controller and motor operation: The signals emitted by the crystal oscillator are used to control the operation of the motor and other actuators. Different frequencies of signals are used in different situations, which is the basis for ensuring the normal operation of the energy storage converter (PCS);

Temperature sensor: Crystal oscillator can also be used as a temperature sensor to monitor the temperature of the power supply environment and assist the system in temperature management;

Energy storage efficiency: Quartz crystal oscillators can efficiently store and instantly release energy in energy storage circuits, with energy storage capabilities. When used as energy storage components, they have short charging and discharging times and high energy storage efficiency;

The roles of crystal oscillators in energy storage NPC systems ensure the stability, reliability, and efficiency of the entire energy storage system.

Considering the working scenario of energy storage itself, choose a crystal oscillator with low frequency deviation (such as ± 30ppm or better) and good temperature stability to ensure the stability of the system clock at different working temperatures.

The application characteristics of EPSON's active crystal oscillator SG3225EEN (X1G005221002300) in energy storage NPC:

1. Within the working temperature range of -40~85 ℃, the total frequency difference is ± 50PPM, with high precision and reliability;

2. 3225 small volume packaging, strong universality, high cost-effectiveness;

3. Compatible with multiple voltages ranging from 2.5-3.3V, and can operate normally within this voltage range;

4. Active crystal oscillators have high stability and provide stable clock signals for clock circuits, suitable for new energy fields such as energy storage NPCs and energy storage boards;
