However, all these features put out many questions in our minds. One needs to change the transformer winding for changing the output voltage in an isolated push-pull converter circuit. A push-pull converter opens up lots of conversion possibilities, such as Buck, Boost, Buck-Boost, isolated, or even non-isolated topologies, also it is one of the oldest switching topologies used in power electronics that require minimum components to produce medium power outputs (Typically - 150W to 500W) with multiple output voltage. This can be done using a boost switching topology where a switching inductor is constantly switched.Īnother costly but useful method is to use a push-pull converter. Now, if a DC-DC converter is used in this place, and the 5V 2A which is 10W output is constant, ideally the DC-DC converter will convert the Voltage to a 10V with a 1A current rating. Now consider a situation where we need to change it to a 10V output for a specific application. Previously we have designed a 5V, 2A SMPS Circuit, you can check that out if that is something you are looking for. An example could be the situation where a 5V output could provide 2A of current. The same goes for switching regulators, the output power (wattage) of any converter is the product of voltage and current, a DC-DC converter ideally converts the voltage, or the current while the wattage is constant. Now from the law of conservation of energy, we know that energy cannot be created nor destroyed, but it only can be transformed. There are mainly two types of major DC-DC conversion topologies available in power electronics, namely, the switching converter and the Linear converter. When it comes to working with power electronics, a DC-DC converter topology becomes very crucial for practical designs.
