Inverter Circuits

This post shows you how to build a converter that changes car battery power 12V DC into household current 220V AC using a chip called the SG3525 and special transistors called MOSFETs. It uses a special method called Pulse Width Modulation PWM to make the AC current. This converter can be used to power regular […]

Our electronics and appliances usually need AC power to work, even if the original source of power is DC like a battery. This is why things like phone chargers and UPS systems battery backups need a special part called an inverter. An inverter changes DC power to AC power. This article shows you how to […]

This post shows you how to build a simple electric fence charger. This is a safe and affordable way to keep your pets inside your yard and wild animals out. It is a good alternative to a regular fence because it is cheaper and easier to fix. WARNING: Electric fences can be dangerous if not […]

This article shows you how to build a powerful inverter that changes car battery power 12V to household current 230 using a modern chip called the IR2153. This chip is better than older designs because: Components needed to build this 500 watt inverter: You can also change the settings on this inverter to use less […]

This article will show you how to build a special kind of generator that makes super high frequency electricity. This lets you do experiments that would not be possible with normal power supplies. One cool thing about this high frequency electricity is that it mostly stays on the surface of your skin if you touch […]
