[Linear and Switched Mode(PWM) AC Power Sources]
Samgor designs and manufactures both linear and switched mode (PWM) Electronics Power Sources. We provide technically advanced, reliable, and cost effective standard and custom precision programmable AC Power Solutions that feature fast transient response, tight regulation, high peak current capability, no switching noise (linear) and low switching noise (PWM switching) models and low output impedance.
The SGVF series linear AC power sources produce low-distortion and high fidelity output waveforms with low partial discharge (<2pC). The advantage of linear amplification is its ability to faithfully reproduce oscillator waveforms with very high small signal bandwidth and low output distortion. The capacity of the linear AC power sources are up to 1000kVA single phase/each unit, it can combination to three phase (Delta or Star) or parallel using for single phase.
The SGVF series PWM AC Power Sources offer very good power density, high efficiency, and perform well into low power factor loads. They use a combination of both linear and non-linear methods to achieve high efficiency conversion in lighter and smaller packages. Using additional power filter, the partial discharge also can be
less than 30pC typically. The capacity of the PWM AC power sources are up to 3000kVA three phase (Delta or Star), 2000kVA single phase.
Both linear and switched mode (PWM) AC Power Sources can adjust voltage and frequency separately . Also it can used as the pure power supply even using at very bad power quality place, the output voltage, frequency and waveform will be special stability.
