DC (Direct Current) Convert to DC Transformer
A DC/DC transformer is a component or device that converts DC (direct current) to DC, specifically referring to a component that utilizes DC to convert from one voltage level to another voltage level. DC/DC is divided into two categories based on voltage level transformation: The transformer that generates a voltage lower than the initial voltage is called a "step-down transformer"; The transformer that generates a voltage higher than the initial voltage is called a "boost transformer". And can also be divided into isolated power supply and non isolated power supply based on input/output relationship. For example, the DC/DC converter connected to the vehicle's DC power supply converts high-voltage DC into low-voltage DC. And electronic components such as ICs have different operating voltage ranges, so they also need to be converted to corresponding voltages.
Specifically, it refers to converting the input DC to AC through the Self-oscillation circuit, and then converting to DC output after changing the voltage through the transformer, or converting AC to high-voltage DC output through the voltage doubling rectifier circuit.
