With the daily use of electrical equipment in the constant increase in the voltage requirements continue to improve, and sometimes when the voltage instability will cause damage to our electrical equipment, but also on our daily lives. In order to make the voltage in our daily use more stable, generally we will increase the installation of switching power supply transformer, the following is a basic introduction of some switching power supply transformers.
Switching power supply transformer is added to the switch management settings of the power transformer, in use not only has the general transformer voltage conversion function, but also both insulation and power transmission function. In the switching power supply and other occasions involving the use of high-frequency circuits are more extensive.
Switching power transformer role
SMPS transformers manufacturer and switch together constitute a self-excited (or his shock) type of intermittent oscillator, thus the input DC voltage modulated into a high-frequency pulse voltage.
Play the role of energy transfer and conversion. In the flyback circuit, when the switch is turned on, the transformer to convert electrical energy into a magnetic field can be stored, when the switch is released when the cut-off. In the forward circuit, when the switch is turned on, the input voltage directly to the load and the energy stored in the energy storage inductor. When the switch-off, and then by the energy storage inductor for continued flow to the load transfer. The input DC voltage into the required variety of low-voltage.
