Power Electronics and Converters
Design Highlights
- SMPS (Switched-Mode Power Supply) with an analog circuit supervised by a microcontroller
- Power stage topology: multiphase step-down (6 phases)
- Air-cooled design
- Output voltage compliant with MIL-STD-704F standard
- Environmental resistance tested according to RTCA-DO-160G standards
P3TP Power Converter
P3TP convertor is a source of electrical energy intended for a 28 VDC electrical power system of small aircrafts. The whole system consists of turboprop (TP100) or turboshaft (TS100) engine, which drives the three-phase highspeed generator its output is converted by the P3TP convertor to 28 VDC with the power of up to 3 kW.
P3TP is designed to be used with generator and engine (TP100 / TS100) produced by the company PBS Velká Bíteš, a.s., Czech Republic.
Key Features:
- SMPS control based on analog circuit design (no SW involved in power generation functionality; SW partly involved in monitoring and CAN communication)
- output power limitation according to engine’s speed
- cooled by the airflow of the suck air of the engine
- constant current at overload (current limitation)
- controls the external contactor (disconnects the convertor from DC BUS in case of failure)
- monitoring – light indicators plus CAN communication
- output voltage complies with MIL-STD-704F standard
- environmental resistance compliant with RTCA DO-160G standard
Electrical Power Distribution Boxes EPDB
EPDB is a set of two distribution boxes inteded for twin engine small aircafts of CS23 category with 28VDC dual-channel electrical system with two batteries and two starter-generators. The main function is the reliable distribution of the electrical energy from airborne systems to airborne loads with respect to the pilot’s requests, the equipment of the aircraft and flight phases. EPDB also provides monitoring and protection of the EPS. The EPDB device is controlled by the switches from the cockpit and is implemented in the EV-55 aircraft.
Key Features:
- Intelligent management of electrical energy
- one or two-channel concept operating possibility
- voltage and current measuremet
- light indicators of EPS state
- automatic functions decreasing pilot's workload
- power outputs short-circuit protection
- overcurrent protection of channels interconnection
- polarity reverse and overvoltage GPU protection
- fail-safe design with regard to AC23.1309
- easy maintenance and service
- high reliability
