Working Principle

When using the PT78ST112H, the input voltage is modified and the output voltage is obtained. DC converters are often referred to as "check points" as they ensure the conversion of voltage to the desired level with minimal loss. First, the DC input of the PT78ST112H is applied. A power conversion stage follows the input voltage. This stage has two components: an inductive device called a transformer, and the power switch. The transformer increases or decreases the input voltage driving the power switch. The switch, then, creates an output voltage by applying or not, the input voltage to the load.

The next stage converts the voltage. This is done by using a converter rectifier. The rectifier is a circuit that converts AC, alternating current, into DC, direct current. With converter rectifiers, the input voltage is subjected to a process called "DC buck". The DC buck subtracts the input voltage from the converter rectifier. It then places that voltage under control.

The last stage, then, applies the output voltage to the load. This stage also uses the power switch to turn on and off the load. The power switch controls the output voltage by "chopping" the input voltage. This is a process that applies a higher voltage to a lower voltage load, while simultaneously switching the power applied,in order to maintain a steady voltage.

PT78ST112H offers a high efficiency, high power output and high reliability. The above-mentioned stages ensure a safe transfer of electricity while minimizing any potential losses. It is a dependable DC converter suitable for a variety of applications in different sectors.
