Pulse switching regulator

Using the output stage switching regulator, repeated switching "on" and "off" state, and energy storage components (capacitors and inductors) together to generate the output voltage. It is adjusted by mcb circuit breaker from the output voltage to adjust the switching timing of the sample to achieve. At a fixed frequency regulator, by adjusting the pulse width of switching voltage regulator electric meter, which is called PWM control. In gated oscillator or a pulse mode voltage regulator, the switching pulse width and frequency remains constant, however, the output switch is "ON" or "OFF" by the feedback control.
Switches and energy storage unit Circuit breaker to the arrangement, the resulting output voltage can be greater or less than the input voltage, and a voltage regulator can be used to generate a plurality of output voltages. In most cases, the same input voltage and output voltage requirements, the pulse (buck) switching regulator than a linear regulator power conversion efficiency. Compensation Compensation --- precision AC power supply (single phase 0.5kVA and above, three-phase 1.5kVA and above) with compensation transformer.
