Zener diodes - Electrónica de potencia

The high power "zener diode" circuit presented here can be used for obtaining a highly accurate, temperature and voltage stabilized outputs from high current sources, safely. The low power zener diodes that we normally use in electronic circuits are specified to work with low currents, and therefore cannot be used for shunting or stabilizing high current supplies. Although higher rated zener diodes are available, these could be relatively expensive. Nonetheless, it is actually possible to make a.......

Though the 555 driver i ve been using is quite good in running the flyback, however the MOSFETs were easily heated up . I ve broken about 3-4 MOSFET since i ve been using it. Therefore, when i was searching for a more robust flyback driver in order to use it as my tesla coil power supply afterwards, i realized that zero voltage switching (ZVS) flyback driver can give high voltage without heating the MOSFET too much ( sometimes even none!). Hence, i turned to ZVS from that instance. The most popu.......

Here the low power 12V transformerless power supply circuit with full-wave rectification. A lot of circuits could be powered straightaway in the electric mains using the support of a series capacitor (C1). The problem with this method is the fact that typically only one half cycle of the mains wave-form can be used to deliver a DC voltage. An obvious option is to wo.......

Transient bus voltages are a significant risk factor to integrated circuits. The maximum breakdown voltage that an integrated circuit may be specified to tolerate is determined by its style and design approach that can be predominantly low for tiny CMOS devices. Introduction Transient or repetitive over voltage circumstances that defeat an IC?s absolute highest voltage spec may possibly irreversibly harm a device. The necessity for over voltage safety is notably prevalent in automobile 12V and 2.......

I am still lingering around flyback transformer and never start my tesla coil design since i am too absorbed and keen to know how does the flyback transformer work. For your information, before i got to have the ferrite c cores from the original flyback transformer from CRT tv, i have purchased four ferrite rods from Ebay as i ve planned to made them into my own handmade ferrite core or frame. As the rods were still in my room and i ve got nothing to do with it therefore i decided to resume to t.......

This is 150W FM transmitter amplifier for 88-108MHz band. The amplifier has two stages using BLF244 mosfet transistor for the first stage which requires 0.5 - 1Watt of RF input to get about 20watts to drive the final stage SD1407 which can push nearly 200 Watts on this design. This design is more or less broadband however I added two variable capacitors after each stage for optimum matching and power output. Make sure the trimmer and the capacitors after the final stage SD1407 are a high voltag.......
