PWM controller with PIC18f2455
The use of pulse width modulation (PWM) is common for the use of controlling power to a particular electrical device. Motor speed control, LED contrast control, power supplies are some of the example usage of PWM. 18 series PIC always...
12v speed controllerdimmer
This versatile circuit functions as a speed controller for a 12V motor with a continuous rating of up to 5A or as a dimmer for a 12V halogen or standard incandescent lamp with a maximum rating of 50W. It adjusts...
Bipolar Regenerative receiver
Contrary to the beliefs of some radio experimenters, a bipolar regenerative design can be made to operate efficiently. The primary concern is the low input impedance of the detector-amplifier bipolar stage; however, this can be effectively compensated with positive feedback...
H Bridge circuit
An H-bridge is a circuit configuration that enables the application of voltages in both directions. It permits higher voltage and current to be applied to the load while controlling the direction using a low voltage signal. The accompanying diagram illustrates...
IR On/Off Switch Using Microcontroller
Turning electrical devices ON or OFF using a remote control is a well-established concept, with numerous devices available that perform this function effectively. To create such a device, it is necessary to construct a receiver and a transmitter, as well...
PWM Generator
A pulse-width modulated (PWM) signal can be generated using a triangle wave and a comparator. The digital-to-analog converter (DAC) serves as the input signal, and the resulting output signal's duty cycle will be proportional to the input voltage. This PWM...
H-bridge driving problemMOSFET frequently damage
An H-bridge is being utilized with IRF740 MOSFETs to convert 315V DC to 230V AC. However, the upper MOSFETs are frequently damaged within a few seconds, and the cause of this issue has not been identified.
The described circuit employs an...
Analog PWM connection with FIG zps-101 interface
An AC-DC-AC circuit utilizes a power transistor as a switching device with analog control, as recommended in the wiring diagram of Figure 6-10. This circuit generates a voltage-controlled oscillator (VCO) using OCT and FCT, with RCT available for OCT delay....
Power supplies for microcontroller based projects
This document discusses the use of small microcontrollers, such as those from the PIC and Atmel series, which typically operate at 5V and require less than 100mA for complete system functionality. Some PICs can function at lower voltages, such as...
