How can I improve my power supply efficiency?

Improving power conversion efficiency is important for saving energy in power supplies. There are many discussions in the field about achieving higher efficiency by implementing techniques such as a digital control loop, using better components, innovative packaging, or optimising thermal management.

What makes a power supply efficient?

The efficiency of a computer power supply is its output power divided by its input power; the remaining input power is converted into heat. For instance, a 600-watt power supply with 60% efficiency running at full load would draw 1000 W from the mains and would therefore waste 400 W as heat.

Which is the most common power supply circuit?

Power Supply Circuit. The most common source of power supply these days is the AC mains, because it is more efficient and economical to generate and transmit AC power. However, DC voltage/current are required for the satisfactory operation of a wide variety of electronics equipment using solid state devices, such as diode, transistors and ICs.

What makes a power supply an efficient power supply?

The specifications, norms and guidelines we just mentioned all call for high efficiency, as well as improved power quality. Power supplies that conform to these demanding rules by passing a defined set of tests may then be marked with the 80 PLUS badge appropriate to their efficiency level.

How to build a simple power supply circuit?

The post details how to design and build a simple power supply circuit right from the basic design to the reasonably sophisticated power supply having extended features. Whether it’s an electronic noob or an expert engineer, all require this indispensable piece of equipment called the power supply unit.

Why do power supplies use a PWM circuit?

However, these power supplies use a PWM circuit to smooth and regulate the output voltage, which requires the use of an active switching component (normally a MOSFET). This means that the system radiates strong EMI, and the output will contain spikes due to switching noise.
