Abstract
PURPOSE:To discriminate the malfunction of a thyristor by providing an inconformity detecting circuit for detecting the inconformity between the voltage signal of the thyristor and a signal corresponding to the applied voltage of a thyristor bulb. CONSTITUTION:When a thyristor 1 is normal, a solid line part 1 of a voltage waveform a is applied to each thyristor, which in turn generates a voltage signal (b). When the thyristor is normal, a signal (c) outputted form an OR circuit 18 becomes entirely the same signal as the voltage signal (b), but an element malfunction signal (d) is not outputted from a inconformity detecting circuit 19. If the thyristor malfunctions, the signal (c) is outputted, but the voltage signal (b) of the malfunctioned thyristor is not outputted. Accordingly, the detecting circuit 19 outputs an element malfunction singnal (d).
