12V to 220V Inverter based MOSFET IRFZ44

Simple 12-220 AC to DC Inverter Circuit MOSFET IRFZ44

Here the 12V to 220V inverter based MOSFET IRFZ44. This DC to AC inverter circuit work according to unstable multivibrator. In this inverter circuit, IC CD4047 is do the job as being a heart of unstable multivibrator, because of the fact that this IC type delivers a complementary output which has opposite phase to another (pin 10 and 11), and has 50 percent duty cycle that satisfy to generate a pulse for inverter.

50W Inverter Circuit 12VDC to 220VAC based MOSFET FQB45N03

12VDC to 220VAC Inverter with Sine Wave Output

Here the 50W inverter circuit build based power MOSFET FQB45N03 and IC TL494. This inverter will convert 12-14V DC input from car battery, become 220V AC output with 50Hz sine wave frequency.

The main oscillator, a voltage reference and comparator collected on DA2. External elements DD1 and DD2 repeated internal structure of the TL494, in the part that works is unstable at low frequencies (false positive D-flip-flop).

Inverter for 8W Fluorescent Lamp

Inverter for 8W Fluorescent Lamp

This is the circuit diagram of inverter for 8W fluorescent lamp. The circuit is build based ZTX652 transistor, and used to drive an 8W fluorescent lamp from a 12V source. The inverter will work from 10V to 16.5V DC supply, attaining efficiencies up to 78% thus making it suitable for use in on-charge systems such as caravans / mobile homes/ RVs as well as periodically charged systems such as roadside lamps, camping lights or outhouse lights etc.

The 270W and 22W resistors bias a ZTX652 transistor into conduction, in which the positive feedback provided to the transistor by W1 drives it into saturation, therefore using the supply voltage across W2. This makes a magnetising current to build up in W2 until finally the transformer’s ferrite core saturates. When this happens, the base drive provided to the transistor by W1 decays, triggering the transistor to immediately turn off.
