Powered by H-bridge Capacitor, 200-1500VDC wide input DC/DC Converters - PV40-29AxxH & PV40-29BxxH

Powered by an H-bridge capacitor, the circuit can reduce overall system costs and improve power supply reliability. MORNSUN launches a new generation of H-bridge power-taking DC/DC Converters with ultra-wide 200-1500VDC input for Static Var Generator. They are the PV40-29A15H with ±15V dual isolated outputs and the PV40-29B15H with a 15V single output.

 

PV40-29A/BxxH series feature a wide operating temperature of -40℃ to +75℃, complete protections, and great EMC performance, and offer a 3-year warranty. Single output and dual isolated outputs are optional. They can be widely used in SVG, photovoltaic inverter, high-voltage inverter, and other H-bridge drive circuit occasions. 

(For the dual isolated outputs module, the non-isolated ±15V outputs can be achieved through external connection of -Vo1 and +Vo2 pin.)

 

Advantages

1. High performance

① Ultra-wide input voltage range: 200-1500VDC, powered by an H-bridge capacitor to simplify system design and improve reliability

② High efficiency of 86%

③ Wide operating temperature range: -40℃~+75℃; Suitable for the complex industrial environment

④ Single output (PV40-29BxxH) / Dual isolated outputs (PV40-29AxxH)

⑤ PV40-29AxxH can be used to provide the non-isolated ±15V outputs by connecting the -Vo1 and +Vo2.

 

2. High reliability

① High isolation voltage: input-output 4000VAC, leakage current ＜ 4mA

② Complete protections: Input under-voltage protection, input reverse polarity protection, output short circuit, over-current, over-voltage protection

③ EMS: Surge meets IEC/EN61000-4-5 Line to line ±1KV Perf. Criteria B, EFT meets IEC/EN61000-4-4 ±4KV Perf. Criteria B

④ Operating altitude up to 5000m, meeting a variety of geographical climate

⑤ Design according to UL1741, EN/BSEN62109-1
