Distributed power systems are commonly used in telecommunications, networking, and high-end server applications, utilizing a 48 V bus voltage derived from the telecom industry. This 48 V bus supplies several isolated point-of-load (POL) converters that power the end loads,...

Since my page was first posted, I have received a number of emails asking about a high current power supply. I looked around, but couldn’t find one that was suitable. So, I designed this. It is a linear supply,...

These circuits are commonly utilized in robotics to enable DC motors to operate in both forward and reverse directions, as well as to provide an electric brake (short circuit condition). H-bridges can be found as integrated circuits or can...

The present trend is to use ever higher frequencies. But by doing so it becomes more difficult to filter out the RF noise inevitably generated by the switching. So I decided to stay at a low switching frequency of...

A remote-controlled alarm circuit utilizing the TSOP1736 is designed for easy use by elderly individuals or patients confined to bed. This battery-operated alarm system eliminates the need for routing electric cables to a calling bell switch, making it a...

The drive circuit for the electromotor comprises a FET bridge circuit, a FET base drive circuit, a current sensor for the motor drive circuit, and a relay. The FET bridge circuit primarily consists of four high-power MOSFETs, which must...
