Description
Single-Phase Transformer & Unipolar Switching Power Supply
1. Single-Phase Transformer
- Definition:A transformer with single-phase windings on both the primary and secondary sides.
- Advantages:
- Simple structure and compact size.
- Low losses, especially minimal core losses (iron losses).
- Ideal for low-voltage distribution networks with lower load density, such as rural grids or decentralized renewable energy systems.
2. Unipolar Switching Power Supply
- Definition:A power supply with unipolar output (positive and negative terminals only), contrasting with bipolar switching power supplies that provide three outputs: positive voltage, negative voltage, and ground.
- Typical Applications:
- Low-voltage DC systems (e.g., LED drivers, IoT devices).
- Cost-sensitive industrial controls requiring simplified power topology.
