In this article I will explain how to upgrade an EGS002 inverter board to 5kVA power level using the HCPL-3120 or HCPL-J312 opto isolated drivers with isolated inputs and isolated power supply stages. However, the low side MOSFETs are driven through ordinary BJT totem pole configuration such as by using BD139 and BD140 transistor pairs. […]

SG3525 Inverter Circuits with Low Battery Cut-off and Overvoltage Regulation
In this post I have explained a 3 powerful yet simple 12V inverter circuits using a single IC SG 3525. The first circuit is equipped with a low battery detection and cut off feature, and an automatic output voltage regulation feature. You may also want to read how to design a sine wave inverter from […]
IC IR2111 H-Bridge Inverter Circuit with Shut Down
This circuit is basically a H bridge inverter where two IC IR2111 are working for driving four MOSFETs that are connected in H bridge way. We also see that there is a overload and over current shut down using BC547 small transistors. So what happens is that we can run a load with AC waveform […]
Pseudo-sinusoidal IC 4047 Inverter Circuit
From a continuous source, battery, or vehicle alternator, it is possible to produce a 50 Hz voltage/pseudo-sinusoidal waveform, using this simple IC 4047 inverter circuit. The design is capable of operating many low-power devices that require a voltage of 220 V AC, typically supplied by the AC mains grid distribution network. The power of this […]
IR2111 H-Bridge Inverter Circuit with Soft Start
Here we see this circuit diagram which is full H-Bridge using 4 power MOSFETs and 2 IR2111 high side driver ICs. That means this circuit is for making full bridge inverter which converts DC into AC. Power Supply Part We have +600V DC at top rail, written as +600V max. And ground (0V) at bottom. […]
