Zero Voltage Switching (ZVS) | Principle | Waveforms
The zero voltage switch is designed to always switch the thyristors (triacs or SCRs) as close as possible to the time when the supply voltage waveform crosses the zero line, or passes through zero. If a thyristor is triggered at the zero crossing, the RFI generated will be almost negligible and this particular disadvantage of phase control is overcome.

Doesn''t that mean the voltage is zero across the terminals of the battery? From Ohm''s law V = IR and when R =0, V = 0. But how is the voltage zero when one terminal of the battery is clearly at a higher potential? The positive charge is concentrated at one terminal and the negative in the other. So how come the voltage becomes zero in a short ...

It is safely impossible to drop an ideal battery to zero volts. A battery cannot go down to zero volts because of the internal chemistry. In a standard use, you cannot drop the voltage below 2 volts, even if you wired the terminals together. Batteries will vary between 3.8 and 2.4 volts per cell. As voltage drops, internal resistance rises. The ...
