What is the working principle of Open Frame?

Open Frame does not generate electrical energy, but converts electrical energy into voltage or current required by various devices, such as mobile phone chargers that convert 220 V network to 5 V DC.

What is the working principle of Open Frame?

Open Frame is an inverter that converts the low voltage input DC into a high voltage AC output through the process of MOS tube switching and transformer amplification. The input DC goes through the fuse and filter capacitor, one of which goes to the moss tube and transformer, and the other via the on-off switch to the IC. The PWM control IC outputs two rectangular wave signals with adjustable pulse width (approx. 50k frequency), drives two moss tubes each, switches on the currents flowing in two opposite directions of the transformer's primary winding, and then amplifies the voltage through the transformer with a greater transmission ratio. a sinusoidal high voltage lighting tube is output. The function of the voltage feedback part is that the IC can protect the output in time if the output voltage is abnormal (e.g., open circuit or lamp ignition); Brightness is stable.

What are the features of Open Frame?

Can be implemented on multiple boards, although it is common to have everything on one board, leaving some space for large transformers, heat sink fans and mechanical mounts, especially high voltage/power supplies. If you are designing a small controller for a board connected to a power supply, you are working in the topology above anyway, you just need to create a ground between the output controller and your new controller connector. This is also common with high current supplies.

What is the workflow of Open Frame?

The working feature of Open Frame is that the communication line is simple as long as a pair of transmission lines can realize two-way communication (the telephone line can be used directly as a transmission line), which significantly reduces the cost and is especially suitable for remote communication, but the transmission speed is slow. The communication method in which the data of each bit of a message is transmitted successively bit by bit is called serial communication. The characteristics of serial communication are: the transmission of data bits takes place in bit order, at least one transmission line can be completed; The cost is low, but the transfer speed is slow. The distance of serial communication can be several meters to several kilometers; According to the direction of information transmission, serial communication can be further divided into three types: simplex, half-duplex and full-duplex.
