How much does a pure sine wave inverter cost?

Decent high power commercial pure sine wave inverters are very expensive! They range from $120-$400. With the EGS002 you can design all sorts of inverters with input voltage, output voltage and power ratings of your choice! For as low as $20, depending on your specs and where you source your components.

How does a pure sine wave inverter work?

A Pure Sine Wave Inverter works in five steps: Input Source: A low-voltage DC supply (12V/24V). Input Source: A low-voltage DC supply (12V/24V). Wave Generation: The EGS002 SPWM (Sinusoidal Pulse Width Modulation) module generates PWM signals. Wave Generation: The EGS002 SPWM (Sinusoidal Pulse Width Modulation) module generates PWM signals.

Can a sine wave inverter produce a square wave output?

Some of them produce a square-wave output, which is undesirable for inductive loads. Here we designed a simple sine wave inverter circuit that produces 50Hz quasi-sine wave output using a single IC CD4047 and some discrete components, which makes it a very cost-effective solution. The DIY sine wave inverter circuit using IC 4047 is given below.

How to convert 12V DC to 220V AC?

Make a full sinusoidal 1000 watts inverter using EGS002 SPWM driver board, which can convert the 12V DC to 220V AC with 50/60Hz pure sine wave.

How much does a square wave inverter cost?

A few years back sine wave inverters were extremely expensive ($200-$1000). As a result square wave and modified square wave were the common and affordable options. Square wave inverters are less efficient and can damage sensitive appliances.

How is sine wave output obtained?

The sine wave output is obtained by forming a tank circuit with the secondary winding of the inverter transformer in parallel with capacitors C5 through C7. Two 2.2µF capacitors are connected to the gates of the MOSFETs in both banks with respect to the ground if proper sinewave is not produced.
