DC DC Converters: JCJ0812D15 Application Field and Working Principle

The JCJ0812D15 DC DC converters can be used in a variety of applications. It is used in the power and electronic applications like renewable energy, automotive, medical, communications, industrial and consumer. The high power density, efficiency and shrinkage size provide advantages in these fields.The DC converters, including JCJ0812D15, are switching DC voltage converters that are used to convert one DC voltage polarity to another DC voltage with a regulated output voltage. It is widely used in electrical circuits due to its high frequency characteristics, small size, and for its ability to easily make voltage adjustments.

Working Principle

DC converters, including JCJ0812D15, are based on the switching principle. The output voltage is regulated and converted to the desired voltage with the help of the switching mechanism. It is achieved by a switching circuit that alternately turns the transformer circuits on and off. This process is called pulsed width modulation, or PWM.The main process of the converter is to control the voltage switch time (PWM). The oscillator frequency (FOSC) must be fixed and must be compared with the feedback voltage. When they differ, the voltage switch time of the switch will be changed. By precisely controlling the PWM ratio, a stable switching power supply can be achieved.In the switching process, the power is transferred to the anode and cathode which are connected to the main circuit. The traditional JCJ0812D15 DC DC converters use two MOSFETs, which are structured as a single half-bridge. Each transistor is turned on and off alternately. When the transistor is on, a current flows through the transistor and the magnetic flux is generated in the transformer. When the transistor is off, the magnetic flux generated in the transformer is reversed and the energy stored in the transformer is transferred to the output circuit.The PWM pulse signal is generated by the controller, which can monitor the output voltage. When the output voltage is too high, the width of the PWM is decreased, and when the output voltage is too low, the width of the PWM is increased. This process ensures that a stable output voltage can be maintained.
