Power transformer for primary switched-mode power supplies in a forward converter circuit. With the aid of four switchable converter valves as well as two fast rectifier diodes, the following primary switched-mode power supply circuits can be implemented:
- Single-phase forward converter
- Push-pull converter with full-wave rectification
- Asymmetric half-bridge forward converter
- Full-bridge forward converter
- Owing to the shield winding the transformer is suitable for generating a reliable protective extra-low voltage in compliance with VDE 0100 (safety standards). The primary windings are equipped with thermal circuit breakers.
