TIDA-050082
High-voltage, positive rail active precharge reference design
TIDA-050082
概覽
This reference design utilizes a buck-converter topology to precharge large high-voltage (HV) DC- link capacitances in hybrid electric vehicles (HEV), electric vehicles (EV), and energy storage systems (ESS). This design expands upon and updates High-Voltage Solid-State Relay Active Precharge Reference Design.
特點
- Charges 2mF capacitance from 0V to 800V within 400ms
- 4.5AAVG, 10APK-PK charging current
- 5kVRMS reinforced isolation
- Integrated isolated bias supply for high-side rail and positive-rail MOSFET or IGBT gate drive
- Integrated comparators for hysteretic current control
已開發完全組裝的電路板，僅供測試與性能驗證，且為非賣品。
