Advantages and disadvantages of non-contact AC voltage regulator

Basic structure: by voltage or current zero crossing switching thyristor leaving one or more groups leaving the compensation Circuit breaker group of one or more of the compensation winding transformer boost, buck, the primary circuit, or switch from Air circuit breaker tap to regulate the output voltage. electric meter: with load capacity, high efficiency, small waveform distortion, fast response time and low noise. Disadvantages: regulation accuracy is not high application: everything you need to place the regulator.
