## 230V 12V, 1A SMPS Circuit Diagram and Connection

### Hey, in this article we are going to see the circuit diagram of a 230V/12V, 1A SMPS. It basically, converts 230V AC supply into 12V DC supply. SMPS means Switched Mode Power Supply. SMPS power supplies are very power efficient, compact in design, and lightweight. The other way to convert 230V AC into 12V DC is by connecting a rectifier circuit with a step-down transformer. But this arrangement is very less power efficient and heavy in weight due to the big transformer size. Nowadays, the use…

## How to Build a High Torque DC Motor Speed Controller Circuit

### Are you fed up with ordinary PWM circuits which do not provide perfect DC motor speed control especially at lower speeds? Then check out this outstanding single chip PWM motor speed controller circuit that will give you a complete 360 degrees of continuously varying motor speed control right from zero to maximum. The speed is controlled through an externally applied varying DC voltage source. The most striking feature of this circuit is its ability to provide full torque even at minimum…
