Panel switch wiring

This Inverter takes 12 volt d.c and steps it up to 120 volt a.c. The wattage depends on which transistors you use for Q1 and Q2, as well as the "Amp Rating" of the transformer you use for T1. This inverter can be constructed to supply anywhere from 1 to 1000 (1 KW) watts. If Q1, Q2 are 2N3055 NPN Transistors and T1 is a 15 A transformer, then the inverter will supply about 300 watts. Larger transformers and more powerful transistors can be substituted for T1, Q1 and Q2 for more power.


Parts
C1, C2 >> 68 uf, 25 V Tantalum Capacitor
R1, R2 >> 10 Ohm, 5 Watt Resistor
R3, R4 >> 180 Ohm, 1 Watt Resistor
D1, D2 >> HEP 154 Silicon Diode
Q1, Q2 >> 2N3055 NPN Transistor (see "Notes")
T1 >> 24V, Center Tapped Transformer
Misc:
Wire, Case, Receptacle (for output)
Fuses, Heatsinks, etc.

Note: Dont try to run inductive loads (motors...) off this inverter.

This circuit is also use operational amplifier IC LM324 to drive the VN64GA with the error signal and to control output voltage. This output voltage is pulsating DC , which is quite satisfactory for battery charging. This circuit also can be converted to the system regulated DC supply.
You do this by increased C2 and anoother electrolytic capacitor is added across the load. The respon time is very fast, determined by the op amp.

Schematic and troubleshooting below :

If the circuit not work , Perhaps the cause of :

• AC cable disconnected
• Transformer is damaged or leaking.
•  Broken or leaky diode.
• Installation of inverted foot elco.
• Instrallation of the components of the upside , particularly on the transistor , examine the placement of the feet emitter , collector and base.
• IC damaged.
• Soldering is less sticky.
• Line PCB damaged.
