Feb 11, 2020 - Explore mihalyzmak's board "power supply" on Pinterest. See more ideas about Electronics projects, Diy electronics and Electronic schematics. The output voltage of the power supply can be set using the potentiometer P1. Galvanic isolation of the feedback is not necessary because the control circuit is connected to the secondary SMPS side and isolated from the mains. Current feedback is fed through the current transformer TR3 into pin 3 of the UC3845 chip.

Nov 21, 2015 · Selamat siang Mas Broo, para Hobi Oprek Elektronika khususnya pada para pemula yang sedang mendalami bidang SMPS (switch mode power supply) kados kulo niki ( seperti saya ini), sepertinya pertama tama harus mengetahui dulu masing - masing fungsi setiap komponen yang akan diaplikasikan kedalam rangkaian SMPS tersebut. In other words, you can use smaller components in your SMPS circuit if you use a sufficiently high PWM switching frequency. Buck-boost SMPS circuit diagram. It is generally assumed that the switching frequency of the PWM signal in your SMPS circuit will be the primary determinant of losses, which are then converted to heat.

the starting pulse to the MC34063 circuit. When the user forces the standby mode via the remote control, it naturally shuts the big SMPS down, but the MC34063 circuit is still alive, consuming very little power to supply the µProcessor and the front panel L.E.D. The measurement results are summarized in the below array (Tamb = 25°C):
