This weekly report summarizes the progress of the Bork-Kron-Thai engineering team. It discusses that the team members shared the work each person is doing, and that the author learned about triac and isolation circuits. The author designed two circuits using an MOC3041 optoisolator triac driver and a MAC4DHM triac device. Next week, the author plans to purchase devices and test circuits.

Weekly Progress
In the last week. My group share work of each a preson. I’m learning
about triac circuit and isolate circuit. I have designed 2 the circuit,
Calcilation, Choose the appropriate equipment with circuit. MOC3041 it
is Optoisolators Triac Driver Output. It works by light, Thereafter it
allows current to flow through and can withstand current and voltage at
higher. Internal components is 1.Anode 2.cathode 3.nc 4.main terminal
5.substrate don’t connect 6.main terminal.
MAC4DHM it is Triac device. I search information about this device.
Sensitive Gate Triac. It can blocking voltageto 600 V. On-State current
rating of 4.0 Amperes RMS at 93 degree celsius and low level triggering
and holding characteristics. Nexy week, I will buy device and test circuit
for in order to use it.
