    Tips: SSR-ordinary type of Triac output and enhanced type of unidirectional SCR anti-parallel output

    In the case of inductive load, when the SSR is turned off by the on-state, a large voltage rise rate dv/dt (commutation dv/dt) will be generated at both ends of the triac due to inconsistent phase of current and voltage. The value exceeding the triac's commutation dv/dt (typically 10V/μs) will lead to delayed turn-off, or even failure. However, the unidirectional triac is unipolar and only affected by satic voltage rising rate dv/dt (typical value 100V/μs). The commutation dv/dt of ordinary type SSR formed by only triac has been greatly improved compared to enhanced SSR composed of two unidirectional SCR in anti-parallel, so the enhanced SSR should be selected in inductive or capacitive load field.
