The switching power transformer is a power transformer that adds the switch tube. In addition to the voltage transformation function of the ordinary transformer in the circuit, it also has both insulation isolation and power transmission functions.
Switch power transformer design
The design of the common switching power transformer is the following four types: 1. The primary series of the power transformer.There is a constant N in the transformer calculation formula called the number ratio ratio. It is the ratio of the primary turns to the secondary turn.2. The secondary series of the power transformer.The secondary series of the power transformer is a combination of two or more transformers when the secondary output voltage is not satisfied when the single power is satisfied.3. The primary parallel of the transformer.The remote control transformers and main transformers (power switch transformers) in many old -fashioned color TVs in different power supply belong to the primary parallel of the transformer.4. The secondary parallel of the transformer.The secondary parallel of the power transformer is an application where the secondary output voltage of a single transformer is the same and the single power cannot be met.
