High Energy Circuits

• Thyristor drive for heaters.
• HV power supply, differential amp.
  
• HV power supply, reference.
  
• HV power supply, block.
  
• HV power supply, supply.
  
• HV power supply, main.
  
• HV power supply, oven.
  
• HV power supply, temp. 

What is High Energy ?

High Energy Power Circuits, Thyristor controls like AC and DC Drives, HV power Design, UPS and Mains Power Inverter. SCR control and Battery Chargers.



As per my understanding High Energy Circuits may be High Power Coupled with High Frequency which has to be handled with great care. Also High Voltage Systems. High Current Supplies and High Frequency Power Products are all High Energy. In other words HV, HC and HF products products independently or in combination are High Energy Systems. This labeling is important for Product Safety reasons as they have be used with extreme caution and with protection for People, Equipment and Workshop.  

Electronic Loads are used to test Power Systems. The types are DC and AC Load Types. Passive and Dynamic Loads.

Here i have just grouped circuits that are of such nature. It has to be done under the guidance of an experienced person. It may not be good for home or college projects. This is good as a reference for servicing, troubleshooting for professionals or understanding concepts.



So use this as reference for repair or to learn. This cannot be used for building or project work. Those who work on these things, should do it under the supervision of a qualified electrician, also put this sign in front of your workbench.

Energy Systems earthing is important for safety and shielding for EMI-EMC-RFI.

Some UPS Background Notes i made 1997. Here is a project by Prof Mark Csele that can help you learn more about Inverters. - Professor Mark Csele - Electronic Projects

I made a sign, the flashy colors is to grab attention, The other graphics are to convey the main message to even persons who cannot read.



Power Supply Regulators and MOSFET Transistor

When you are working with High Voltage Systems in the Company Lab, Put this as a Caution sign.

• UPS with AVR, charger. 
  
• UPS with AVR, 2N2646. 
  
• UPS with AVR, main. 
  
• UPS with AVR, alarm. 
  
• UPS with AVR, track.
