3 Best Transformerless Inverter Circuits

3kva sinewave inverters full bridge circuit

The post helps us to understand 3 inverter circuits designed to work without a transformer, and using a full bridge IC network and a SPWM generator circuit. The first idea as given below was requested by Mr. Ralph Wiechert Main Specifications Greetings from Saint Louis, Missouri. Would you be willing to collaborate on an inverter project? … Read more3 Best Transformerless Inverter Circuits

Transformerless AC Voltmeter Circuit Using Arduino

1uF 50V electrolytic capacitor image

In this article we learn how to make a transformerless AC voltmeter using Arduino. Making an analog voltmeter is not an easy task as to build one you must have good knowledge of physical quantities like torque, speed; which can be very difficult when it comes to their practical applications. By Ankit Negi But a … Read moreTransformerless AC Voltmeter Circuit Using Arduino

Transformerless PWM Mains Voltage Stabilizer Circuit

The post discusses a simple circuit design which ensures a perfectly stabilized mains voltage across the connected load, without using relays or transformers, rather by the use of accurately dimensioned and self adjusting PWM pulses. The idea was requested by Mr. Mathew. Technical Specifications About power optimizer (stabilizer) I need a simple circuit board which … Read moreTransformerless PWM Mains Voltage Stabilizer Circuit

Transformerless Constant Current LED Driver Circuit

In this post we learn how just a single IC MBI6001 can be used as a transformerless constant current LED driver circuit for illuminating a chain of many LED in series. The MBI6001 series of ICs are designed to work with mains AC inputs and convert it into a lower voltage DC output which may … Read moreTransformerless Constant Current LED Driver Circuit

Zero Crossing Transformerless Power Supply Circuit

The post explains the importance of a zero crossing detection in capacitive transformerless power supplies in order to make it completely safe from the mains switch ON inrush surge currents. The idea was proposed by Mr. Francis. Technical Specifications I have been reading about the transformer less power supply articles on your site with great … Read moreZero Crossing Transformerless Power Supply Circuit

Switching Transformerless Power Supply using IC 555

A simple yet smart solution is implemented here using IC 555 in its monostable mode to control in rush surge in a  transfomerless power supply via a zero crossing switching circuit concept, wherein the input power from the mains is allowed to enter the circuit only during the zero crossings of the AC signal, thereby eliminating the … Read moreSwitching Transformerless Power Supply using IC 555
