What kind of DC power should new energy car charger choose

New energy car chargers should choose DC power with high output power, safety and reliability, good load characteristics and stability. The commonly used DC power supply is matrix power supply, transformer power supply, DC-DC converter power supply and so on.

Types of DC power supply are:
1. Transformer DC power supply: can provide high voltage DC power supply, has high stability and reliability, but the cost is relatively high.
2. Linear power supply: can provide low-voltage DC power supply, low cost, but low stability.
3. Rectifier power supply: can provide moderate voltage DC power supply, with high stability and reliability, but relatively high cost.
4. Inverter type DC power supply: can provide high voltage DC power supply, has high stability and reliability, but the cost is relatively high.
