Advantages of Advice Capacitor Charging Power Supplies over competitors  chargers:

 

ADVICE capacitor chargers are a new design using the

Advanced Silicon and magnetics components that provide:

• Advice Capacitors Chargers Higher efficiency around 8% over the exist chargers, (reduced temperature rise, increased reliability).

• Function at higher frequency and 50% duty cycle, (Fast response, less noise).

• Shut down if the output voltage is equal or less than 80% of its maximum rate for more than 5 second (higher charge discharge cycle).

• Fully isolated input to output (can be connected directly to the AC line).

• Advice Capacitor Chargers Can provide per request up to 3KW using the standard platform.

Principles of operation of our Capacitor Charging Power Supplies

The capacitor charger tested as a charger that defined by charge time to charge a specific capacitor to requested voltage.

The capacitor charger has a three mode of operation as shown below

​

The rate of which the capacitor charger is charged and discharged is called the repetition rate , T , and may vary from 0.01Hz for large capacitor banks to a few KHz .

A capacitor charging has two power rating expressed in Joule per second (J/S)

The peak power rating is used when calculate the charge time and the average power is used to determine the maximum repetition rate.

​

The charge time calculated by using the formula: 

 

T (second) =

Where:

T = Charge time in second

C = Capacitor in farads

V = Charge voltage require

Ppeak = Unit peak power (J/S)

 

The average output power depends on the discharge mode energy and repetition rate of the load

 

P (J/S) = Wload / T (w=energy delivered per charging cycle T=repetition rate).
