Chassis Mount AudioTransformer Isolation Transformer/Step up and down Transformer

Description

100watt 200watt isolation transformer are used to propagate signal voltage and signal power, and can also achieve impedance matching between circuits, and have an isolation effect on direct current. There is no difference in principle between a high-frequency transformer and a low-frequency transformer. However, due to the different frequencies of high frequency and low frequency, the iron core used in the transformer is different. Low-frequency transformers generally use high-permeability silicon steel sheets, and high-frequency transformers use high-frequency ferrite cores.

characteristics

1. The AC power input is rectified and filtered into DC;

2. The switching tube is controlled by a high-frequency PWM (pulse width modulation) signal, and that DC is added to the primary of the switching transformer;

3. The secondary of the switching transformer induces a high-frequency voltage, Rectification and filtering supply the load;

4. The output part is fed back to the control circuit through a certain circuit to control the PWM duty cycle to achieve the purpose of stable output. When the AC power is input, it generally needs to pass through something like a current loop to filter out the interference on the grid, and at the same time filter the interference of the power supply to the grid; when the power is the same, the higher the switching frequency, the smaller the volume of the switching transformer. But the higher the requirements for the switching tube; the secondary of the switching transformer can have multiple windings or one winding with multiple taps to obtain the required output; generally, some protection circuits should be added, such as no-load, short-circuit protection, etc. Otherwise, the switching power supply may be burnt.
