Modular power supply VHP800-C60 Series

AC/DCDC/DCadjustable

- High-performance control strategy. - High-performance control algorithms. - Soft-start adjustment in the full load section. - High power density. - High-efficiency topology. - Quick Response. The IGBT power module adopts a two-stage scheme, with wide voltage and current range to deliver high efficiency, low interference and high precision. Power density is improved through water cooling so it is especially suitable for low-voltage and high-current occasions requiring adjustable output voltage and current, which provides safe, efficient and stable power supply for the green electricity hydrogen production. High-performance control strategy The main control system of the power supply adopts 6-pulse uncontrolled rectification + interleaved three-phase DC-DC structure for high control accuracy; And the digital controller adopts ARM architecture for fast computing and processing. • High control accuracy PID, digital filtering, constant voltage and current control and fault protection algorithms together realize high performance digital control. • Quick processing Precise ARM chip allows operation speed up to 550MHz. • Multiple applications AC/DC+DC/DC topology is adopted for flexible power supply. And PWM technology lowers grid current harmonic down to 3% to minimize its pollution. High-performance control algorithms The voltage loop uses a feedback notch algorithm to filter out the industrial frequency ripple interference due to uncontrolled rectifier to reduce the output ripple.
