开关式电源模块.jpgIn many applications, regulations apply in various countries to regulate the standby consumption of the devices. This is often difficult to achieve with conventional transformers. The advantages of a power source with a switched-mode power supply are obvious here. Since power is transmitted at a higher frequency here, the volume of the magnetic core can be reduced for the same power in order to minimize power loss and size. Encapsulated Switch-Mode Power Modules (SMPS) are used in a myriad of different applications to ensure an efficient energy supply.

ZETTLERs industry-leading magnetic components are designed for use in a wide area of electronic applications requiring an energy-saving, small and economic power source.

In conventional power supplies a linear regulator provides the desired output voltage by dissipating excess electric power in form of heat, and hence its maximum power efficiency is given by the ratio of input to output voltage.

A Switch Mode Power Supply (SMPS) regulates its output voltage by switching energy storage elements such as inductors, by means of a transistor changing “on” and “off” states at high frequencies. In this mode of operation, the transistor has a very low resistance in its “on” state, thus enabling the converters to operate with high efficiency. The PWM duty cycle of the transistor is controlled by an integrated circuit ensuring proper output voltage regulation.

For mains input Switch Mode Power Supplies the necessary isolation is achieved by the built-in transformer which also acts as a mutual inductor for energy storage. Due to the high switching frequency this transformer can be of a much smaller size compared to 50/60Hz iron core types. This results in compact and light weight supplies, enabling applications with high power density.

Switch Mode Power Supplies come in various topologies, all with their specific advantages for certain applications and output power ranges. In the low to medium output power range, Flyback Switch Mode Power Supplies provide a solid and cost-effective solution for a wide array of demands.
