7000 watt regulator, Perfect and Smoothly Working regulator with Volt meter 

The components called to build this AC regulator (ac regulators) are BTA41-600B TRIAC , 10k resistor, DB3 diac, 104k capacitor (275-400V) , 220k potentiometer, and an ac voltmeter . The process of designing a triac diagram using all these components is involved in the following steps:

1. Description of Components and Circuit:

BTA41-600B TRIAC: This is the high power 40A/600V-rated TRIAC acting as the main switch to interrupt power delivered to the load by adjusting the AC input phase.

DB3 Diac: Further, some related products include the TRIAC and DB3 Diac. The TRIAC is operated when the voltage across a capacitor in an RC network exceeds a preset level.

10k Resistor: Restricts the current within the gate circuit of TRIAC to trigger it correctly.

220k Pot: allowed phase (rotate outside) adjust output voltage. The variation of the charging time of the capacitor, which in turn varies the firing angle of the TRIAC, is done by this element with the capacitor and resistor.

Capacitors 104k x 2 Capacitors (275-400V): These are the inots of the snubber network. This is in order to avoid voltage surges and therefore to protect the TRIAC.

AC Voltmeter 250V: A digital or analog meter to display the regulated voltage output.

***Pinout***

 You need these components for the 7000W 250V AC regulator:

• BTA41-600B TRIAC (600V, 40A)
• Resistor 10k
• DB3 Diac
• Capacitor 104j x 2 (275-400V)
• 220k Potentiometer
• AC Voltmeter

2.Circuit Operation:

The principle of AC regulation is phase angle control. The AC voltage waveform is a set of cycles, and controlling how long the TRIAC conducts in each cycle lets us control how much power is delivered to the load.

Phase Control: These components, along with the 220k potentiometer, set the time it takes to charge the capacitor; even though this is not exact, you may use some tuning. As the capacitor charges up, you should pass the breakdown voltage of diac DB3, and that will in turn trigger TRIAC to conduct current from S1 and flow through your load.

Output Voltage Adjustment: As the 220kΩ pot is varied, the charge rate of the capacitor changes depending upon which subsequently moves/changes the firing point of TRIAC across the AC cycle. Limiting the amount of each AC cycle that actually reaches the load in turn limits how much voltage we get out of the output.

3.Power Handling:

BTA41-600B maximum output power: 7000W (300V AC). Correct heat sinking is necessary to prevent the TRIAC from exceeding its thermal limit when passing a high load current.

4. Snubber Circuit:

These two 104k capacitor (275V) snubbers protect the TRIAC from high voltage transients that could otherwise damage it. These are connected in parallel to the TRIAC.

5. Safety and Final Assembly:

Make sure all components are rated for the correct voltage and power. This PCB is for high-power applications; there are wide spaces needed between parts and insulation to protect it from possible shorting or malfunctions.
