New energy transformer

A. Overview
It is often used to convert the battery's electrical matching inverter circuit into an AC voltage and inverter into a commercial transformer through an inverter transformer. It needs to be used together with the inverter circuit.
B. Features
The toroidal transformer used for the inverter power source has the characteristics of high power efficiency, low working loss, small voltage drop, small volume, transformer installation space can be designed according to requirements, and has good cost performance.
C. Design Considerations
1. Low leakage current
2. High work efficiency
3. Low working loss
4. Small voltage drop
5. Thermal protection
6. Low vibration and noise
7. International Power Transformer Safety Standard
8. Power 10VA to 10KVA
D. Temperature resistance level and temperature rise
Typically we design that over ambient of 25°C, product temperature rise is as follows:
1. Temperature rise below 60°C
2. Temperature rise below 75°C
3. Temperature rise below 95°C
4. Temperature rise below 125°C
5. Or suitable temperature grade and suitable temperature rise
E. Compliance Standard
IEC61558
F. Design required parameters
1. Input voltage (V)
2. Working frequency (Hz)
3. Output voltage (V)
4. Output current (A) or output power (W)
5. Transformer installation space
6. Transformer installation and connection method
7. Requirements of temperature resistance level, efficiency, power consumption
