Ferrite core inductor design calculator
This means you don't have to make a complex ferrite core based transformer. In the above simple 12V to 220V AC ferrite inverter circuit we can see a ready made 12V to 310V DC converter module being used. The complete circuit diagram can be witnessed below: 400V, 10 amp MOSFET IRF740 Specifications
#FERRITE CORE INDUCTOR DESIGN CALCULATOR DRIVER#
This circuit does not employ any specialized driver IC, rather works with only n-channel MOSFETS, and a bootstrapping stage. UPDATE: You may want to jump directly to the new updated " SIMPLIFIED DESIGN", near the bottom of this article, which explains a one-step technique for obtaining a transformerless 5 kva sine wave output instead of going through a complex two-step process as discussed in the concepts below:īefore we learn the 5kva version here's a simpler circuit design for the newcomers. For example if we use a transistor based H-bridge then we may need this oscillator stage to operate the High and low side mosfets accordingly. This oscillator is actually optional and may be required for H-bridge circuits which do not have its own oscillator. We can also see a 50 Hz oscillator stage powered by the same DC source. This is achieved using a bridge rectifier stage, which converts the high frequency 220V into 310 V DC.įinally, this 310 V DC bus voltage is converted back into 220 V 50 Hz using the H-bridge. However, for this the H-bridge stage would need a peak value of the 220V RMS, which is around 310V DC. This is implemented through an H-bridge inverter stage, which converts this high frequency into output into the desired 220V AC. The input DC which could be through a 12V, 24V or 48V battery or solar panel is applied to a ferrite based inverter, which converts it into a high frequency 220V AC output, at around 50 kHz.īut since 50 kHz frequency may not be suitable for our home appliances, we need to convert this high frequency AC into the required 50 Hz / 220V, or 120V AC / 60Hz. Understanding the above block diagram is quite simple: Please note you can convert this ferrite core inverter to any desired wattage, right from 100 watt to 5 kva or as per your own preference.
