PWM Control Dimming Halogen Lamp
The PWM control dimming circuit for a halogen lamp is illustrated. The halogen lamp operates at a rated voltage of 12V with a nominal power of 20W. This dimmer circuit is capable of adjusting the intensity of the halogen lamp...
Internal functional block diagram of NCP5201
The NCP5201 chip contains two sets of PWM signal generating circuits, each with a dedicated set of output pins. These circuits produce two opposite phase PWM signals, which are applied to the gates of three field effect transistors. This arrangement...
DC motor excitation current circuit
FIG T is the excitation transformer, R is a varistor, and there are rectifier diodes to protect against breakdowns from VDii to VD16; Rz and C2 provide resistive-capacitive protection. The circuit is designed to absorb voltage from the magnetic field...
TLE6282 H-Bridge And Half Bridge Driver IC
The converter utilizes a TinySwitch-III family member (U2, a TNY279PN) to deliver up to 1.8 A of load current to six high-intensity Luxeon LEDs (LXHL series). The output voltage is slightly below the forward voltage drop of the LEDs, enabling...
Design of Temperature-Controlled PWM Boost Converter Circuit
A temperature-controlled pulse-width-modulator (PWM) boost converter circuit diagram is illustrated in the following figure. This boost converter is designed to operate a 12V fan using a 5V supply while maintaining temperature control.
The temperature-controlled PWM boost converter circuit operates by stepping...
DC Motor Control Circuit
S1 and S2 are normally open, push-to-close, momentary switches. The diodes may be red or green and serve solely as indicators of direction. The TIP31 transistors may need to be adjusted based on the motor specifications. It is important to...
DC motor servo control circuit diagram
In the circuit, when E and O are input DC voltages, the motor moves to a position corresponding to the voltage. A potentiometer, coaxially connected to the motor, is used for position feedback. When the given voltage equals the wiper...
5V / 2A isolated switching power supply circuit diagram
The circuit diagram includes an input filter capacitor C1 and a primary clamp composed of VDz and VD1. The resistor R1 is connected to the control terminal. C2 serves as a bypass capacitor. The TOP414GC-S is connected in parallel to...
Motor Control circuit II
This circuit is 12 volt motors and lights well regulated. The scheme operates with PWM (Pulse Width Modulation). By IC1, a 555 is a square wave generated by a controllable duty cycle. This means that the width of the pulse...
