Tips: Types of SSR based on trigger form
Based on trigger form, SSR can be divided into zero-voltage type (Z) and phase modulation type (P). When the appropriate control signal VIN is applied at the input, the P-type SSR turns on immediately. When VIN is undone, SSR turns off when the load current drops below the triac's holding current (AC commutation). Z-type SSR includes a zero-crossing detection circuit internally. When the input signal VIN is applied, the SSR can be turned on only when the load supply voltage reaches the zero-crossing region, which may cause the maximum delay, half a cycle, of the power supply. Z-type SSR has the same turn-off criterion as P-type. But because of its approximate sinusoidal load work current and weak higher harmonic interference, Z-type SSR has been widely used.
