Simple 100W inverter schematic design

This document provides an explanation of a simple 100-watt inverter circuit using the IC CD4047 and the IRF540 MOSFET. The circuit is designed to be simple, cost-effective, and suitable for assembly on a veroboard. The CD4047 is a low-power CMOS astable/monostable multivibrator IC, which in this configuration produces two pulse sequences on pins 10 and 11, with a phase difference of 180 degrees. Pin 10 is connected to the gates of Q1, while pin 11 is connected to the gate of Q2. Resistors R3 and R4 are included to prevent loading each MOSFET IC. In the first quarter cycle, the AC voltage output allows current to flow through the upper half of the transformer primary, while in the second quarter, the current flows in the opposite direction through the lower half of the transformer primary, generating the negative half of the output AC voltage. The circuit can utilize a 12V/6AH lead-acid battery for power. It is essential to install appropriate heat sinks for Q1 and Q2. The transformer T1 can be a 230V, 150VA model with suitable primary and secondary windings. The circuit is intended for low-grade applications and should not be expected to perform beyond its simplicity.

The inverter circuit operates by utilizing the CD4047 IC, which serves as the heart of the system, generating square wave signals necessary for driving the MOSFETs. The astable mode of the CD4047 is configured to produce a continuous square wave output, which is essential for the switching operation of the MOSFETs Q1 and Q2. The output frequency can be adjusted by selecting appropriate resistor and capacitor values connected to the CD4047.

The IRF540 MOSFETs are chosen for their ability to handle high currents and voltages, making them suitable for this inverter application. Proper heat sinking is crucial to prevent thermal damage during operation, as the MOSFETs will dissipate heat when switching high currents.

The transformer used in this circuit is a critical component, as it steps up the voltage to the desired output level. A transformer rated for 230V and 150VA is recommended to handle the power requirements efficiently. The primary and secondary windings must be correctly configured to ensure proper operation and safety.

Safety precautions should be observed while assembling and testing the circuit. The use of a lead-acid battery provides a reliable power source, but care must be taken to avoid over-discharging the battery, which can lead to reduced lifespan. The circuit is designed for low-power applications and is suitable for educational purposes or small-scale projects.Explanation Here is a simple 100-watt using IC CD4047 and IRF540 MOSFET of the inverter circuit diagram.

Pin 10 is connected to the gates of Q1 and pin 11 is connected to the gate of Q2. Resistors R3 and R4 prevent loading of each MOSFET IC. When the first 10 feet were accounted for output AC voltage current to flow through the upper half of the positive half of the transformer primary high in the first quarter.

When the second quarter by 11 feet high current flows in the opposite direction through the lower half of the transformer primary, account negative half its output AC voltage. Schematic Precautions B1 can be a 12V/6AH lead-acid batteries. Q1 and Q2 must install the appropriate heat sink. 9-0-V T1 may be a primary, secondary, 230V 150VA transformer. Do not expect from this circuit. It is very simple for low-grade applications.
