CCM Capacitor Charging Module Power Supply

Genvolt’s CCM Series of high voltage modules provides users with a form, fit and function replacement for presently available commercially made units, while providing superior features and benefits at competitive pricing. Utilising proprietary power conversion technology and unique high voltage packaging, these SMT-based high voltage modules provide improved performance and easier system integration at a lower cost when compared to the competition.

Advanced Power Conversion Topology

CCM has been designed for input voltage from 110Vac to 260Vac with integrated power factor correction circuits. The converter uses a proprietary resonant power conversion topology providing exceptional efficiency and inherent low noise and ripple outputs. Due to the fixed, high-frequency conversion rate of the converter, the output capacitance is small, resulting in minimal stored energy and fast rise times. Through the use of generously rated surge limiting resistors and a fast-acting current loop, all units are fully arc and short circuit protected.

Control and Regulation

The power supply is monitored by a microcontroller-based circuit. The actual output voltage generated is sampled via a high impedance divider to create a voltage feedback signal. A current feedback signal is created via a current sense resistor being placed in the low-end return of the high-voltage output circuitry. These two accurate ground-referenced feedback signals are used to precisely regulate and control the unit’s output. The high-bandwidth operational amplifier and high amplification loop parameters make the loop response very fast, and the overcharge is very low.

User Interface

The CCM power supply provides a standard DB15 user interface, which has the functions of output voltage and current setting, and output voltage and current monitoring. There is also an EOC function. When the voltage reaches the set value, EOC outputs a low-level pulse.
