There are three switching power supply keys: unregulated (also known as brute force), linear regulated, and switched. The fourth type of power supply circuit, called ripple adjustment, is an intermediate combination of the design scheme and the "switch" design scheme, which has a sub-project of its own. Non-standard power supplies are the basic kind, consisting of converters, ballasts, and low-pass filters. These types of power supplies typically exhibit a lot of ripple operating voltage (i.e., asymmetrical variations in velocity) and other AC and communication "noise" that accumulates on the DC regulated power supply.
Linear regulated power supply is only a "brute force" (not regulated) power supply, after the "positive" or "linear" way to work the transistor power supply circuit, so the name of linear controller typical linear regulated power supply designed to output a fixed voltage in a wide range of input voltage, and it will simply reduce a lot of unnecessary input voltage, Let the load get the output voltage.
This type of current that is too large will conduct which means it won't be able to keep the voltage steady. It only reduces excessive voltage, but can not fill the supply circuit part of the voltage is not enough. Therefore, depending on the type of controller, the input voltage must be at least 1 to 3 volts higher than the desired output. This represents at least the equivalent of 1 to 3 volts minus the loaded current will be mismatched according to the controller's power circuit, resulting in a lot of heat.
This makes linear regulated power supplies very inefficient. And for heat, they used large heat pipe radiators, which made them bigger and bigger. Light weight, high efficiency, low price, and "clean", smooth output voltage.
