4 Efficient PWM Amplifier Circuits Explained
Audio amplifiers which are designed to amplify an analogue audio signal through pulse width modulation or PWM processing and with adjustable duty cycle is known by many names including digital amplifier, Class-D amplifier, switched amplifier and PWM amplifier. (Article Contributed by: Ritu khanna) Because it can perform at high efficiencies, a Class-D amplifier has become […]
Ultrasonic Fire Alarm Circuit using Air Turbulence Detection
The simple ultrasonic fire alarm circuit I have explained below detects a fire hazard situation by picking up the variations in the surrounding air waves, or the air turbulence. The high sensitivity of the circuit ensures that even the slightest of air turbulence created by a temperature difference or fire is quickly detected and an […]
Using MOSFET Body Diodes to Charge Battery in Inverters
In this post I have explained how the internal body diodes of MOSFETs could be exploited for enabling the charging of battery through the same transformer which is being used as the inverter transformer. In this article we will investigate a full bridge inverter concept and learn how the in-built diodes of its 4 MOSFETs […]
