When the triac is off, you don't use any power, free or otherwise when the triac is on, the current drawn will be the same as when driving a load fully, ie maximum this instantaneous current will exceed the energy being produced by the solar panels. Design ac power control using triac and diac. Where p is the triac power (w), v o is the triac knee voltage (v), i triac avg is the average load current (a), r s is the triac slope resistance (ω) and i triac rms is the root-mean-square (rms) load current (a.
What is a triac the bidirectionality power makes the triac be a very convenient switch or key for circuit ac, also allowing you to control large amounts of power with just a few milliamps of current. Use the heat sink on the triac because of th e power dissipation the triac heat sink can be as large as it needs to be because there is enough place on the board. Applications of triac triac as a high power switch phase control using triac triac vs scr the triac is a bidirectional switching device that can control the ac power efficiently and accurately.
